Similar to as described in General Procedure G, ethyl 9-bromo-4-methyl-4,5-dihydrobenzo[2,3]oxepino[4,5-d]thiazole-2-carboxylate was reacted with (R)-2-(pyridin-2-yl)but-3-yn-2-ol to give a diasteromeric mixture of ethyl 94(R)-3-hydroxy-3-(pyridin-2-yl)but-1-yn-1-yl)-4-methyl-4,5-dihydrobenzo[2,3]oxepino[4,5-d]thiazole-2-carboxylate. Following aminolysis of the ethyl ester (similar to as described in General Procedure M) a diasteromeric mixture of the titled compounds was obtained and separated by Prep HPLC.
