The present disclosure relates, in general, to improved processes for the preparation of 4-{8-amino-3-[(2S)-1-(but-2-ynoyl)pyrrolidin-2-yl]imidazo[1,5-a]pyrazin-1-yl}-N-(pyridin-2-yl)-benzamide, particularly large-scale processes for manufacturing 4-{8-amino-3-[(2S)-1-(but-2-ynoyl)pyrrolidin-2-yl]imidazo[1,5-a]pyrazin-1-yl}-N-(pyridin-2-yl)benzamide and intermediates used in such processes.

The disclosure provides certain porous polymeric membranes, coated with cross-linked polymerized monomers, comprising monomers having a charge when immersed in an organic liquid. The membranes of the disclosure are useful in removing trace amounts of metallic impurities thereby providing ultra-pure organic liquids.

This invention is related to an improvement in the process of filtrate extension of a reaction where at least a set of filtrates of a set of reaction are mixed together to form for a filtrate extension thereby the reaction yields higher order chemical auxiliaries and the reaction is observed that either as convergent or divergent pathway substrate reacts to give qualitative products quantitative, conversions and very less in numbers. Among qualitative conversion reaction filtrate takes pivotal role in synthesizing chemical auxiliaries.
