PROCESSES FOR THE SYNTHESIS OF BAZEDOXIFENE ACETATE AND INTERMEDIATES THEREOF

摘要

Efficient processes for the synthesis of pharmaceutically useful compounds such as (1-[4-(2-azepan-1-yl-ethoxy)-benzyl]-2-(4-hydroxy-phenyl)-3-methyl-1 H-indol-5-ol acetic acid commonly known as bazedoxifene acetate (Formula IX) using cyanomethoxybenzyl halides of Formula III, where X = Halogens e.g., Cl, F, Br, I; G = Any electron donating or electron withdrawing substituent.
