(S)-2-tert-butoxy-2-(7-(4-chlorophenyl)-5-methyl-2-(5-methylindolin-1-yl)benzo[d]thiazol-6-yl)acetic acid was prepared in similar manner as (S)-2-tert-butoxy-2-(7-(4-chlorophenyl)-5-methyl-2-(2-(3-oxo-1H-pyrrolo[3,4-c]pyridin-2(3H)-yl)pyridin-4-yl)benzo[d]thiazol-6-yl)acetic acid except (S)-ethyl 2-(2-bromo-7-(4-chlorophenyl)-5-methylbenzo[d]thiazol-6-yl)-2-tert-butoxyacetate was used instead of (S)-ethyl 2-tert-butoxy-2-(7-(4-chlorophenyl)-2-(2-chloropyridin-4-yl)-5-methylbenzo[d]thiazol-6-yl)acetate, 5-Methylindoline was used instead 1H-pyrrolo[3,4-c]pyridin-3(2H)-one and Pd(P-tBu3)2 was used instead of Pd2(dba)3.
