The present invention relates to a process for preparing the Alectinib or a pharmaceutically acceptable salt thereof using lesser reaction steps and also eliminating expensive and time-consuming column chromatography. The invention also relates to novel polymorphic forms of Alectinib and Alectinib hydrochloride.

A method of preparing Compound (1) or a pharmaceutically acceptable salt thereof: ##STR00001##
comprises: (a) reacting Compound (X): ##STR00002##
or a pharmaceutically acceptable salt thereof with Compound (Y): ##STR00003##
in the presence of a palladium catalyst and a carbonate or phosphate base to form compound (Z): ##STR00004##
or a pharmaceutically acceptable salt thereof; and (b) deprotecting the Ts group of Compound (Z) to form Compound (1) or a pharmaceutically acceptable salt thereof.

The present invention relates to novel poly(heptazine imides), a photocatalytic system comprising such poly(heptazine imides) and a sulfur source as well as the application thereof in photocatalytic reactions.
