Provided are ibrutinib polymorphs, e.g., crystalline ibrutinib Forms III, IV, V, VI, VII, VIII and Form IX and processes for producing these crystalline forms, stable amorphous ibrutinib and processes for preparing stable amorphous ibrutinib, pharmaceutical compositions comprising these forms and methods of using these crystalline and amorphous forms.

The present invention provides a process for the preparation of baricitinib and an intermediate thereof. The present invention provides a convenient, economical, and industrially advantageous two-step process for the preparation of [4-(IH-pyrazol-4-yl)-7Hpyrrolo[2,3-d] pyrimidin-7-yl]methyl pivalate of Formula (II). The process of the present invention involves the use of an alkali or alkaline earth metal hydroxide, carbonate, or bicarbonate as a base for reacting 4-chloro-7H-pyrrolo[2,3-d]pyrimidine of Formula (III) with chloromethyl pivalate of Formula (IV), and the use of an unprotected pyrazole borolane of Formula (VIII) for the conversion of (4-chloro-7H-pyrrolo[2,3-d] pyrimidin-7-yl)methyl 2,2-dimethylpropanoate of Formula V into [4-(1H-pyrazol-4-yl)-7Hpyrrolo[2,3-d]pyrimidin-7-yl]methyl pivalate of Formula (II). The process of the present invention provides [4-(1H-pyrazol-4-yl)-7H-pyrrolo[2,3-d]pyrimidin-7-yl]methyl pivalate of Formula (I) in high yield.

The present invention provides novel crystalline forms of Xevinapant and preparation methods thereof, pharmaceutical compositions containing the crystalline forms, and uses of the crystalline forms for preparing IAPs drugs and drugs for treating LA SCCHN. ##STR00001##

The present invention relates to new piperidine inhibitors of Janus kinase 3 activity, pharmaceutical compositions thereof, and methods of use thereof. ##STR00001##

The present invention provides efficient, economical, and improved methods for synthesizing ibrutinib and intermediates thereof. The invention involves a unique biphasic acylation reaction system which advantageously allows for easy separation of ibrutinib from the reaction mixture without additional extraction and wash steps. The isolated ibrutinib formed using the methods described herein can be useful in the preparation of an amorphous form of ibrutinib. In some embodiments, the isolated ibrutinib produced by the processes described herein is a homogenous solution of ibrutinib and DMSO which may be directly used in the formation of the amorphous polymorph. In some embodiments, the isolated ibrutinib is solid ibrutinib. The solid ibrutinib may also be used in the formation of amorphous ibrutinib.

The present invention provides chimeric compounds that modulate protein function, to restore protein homeostasis, including cytokine, aiolos, and/or ikaros activity, TNF-alpha activity, CK1-alpha activity and cell-cell adhesion. The invention provides methods of modulating protein-mediated diseases, such as cytokine-mediated diseases, disorders, conditions, or responses. Compositions, including in combination with other cytokine and inflammatory mediators, are provided. Methods of treatment, amelioration, or prevention of protein-mediated diseases, disorders, and conditions, such as cytokine-mediated diseases, disorders, and conditions, including inflammation, fibromyalgia, rheumatoid arthritis, osteoarthritis, ankylosing spondylitis, psoriasis, psoriatic arthritis, inflammatory bowel diseases, Crohn's disease, ulcerative colitis, uveitis, inflammatory lung diseases, chronic obstructive pulmonary disease, Alzheimer's disease, organ transplant rejection, and cancer, are provided.
