Reaction Steps
Similar to as described in General Procedure G, racemic ethyl 9-bromo-8-fluoro-4-hydroxy-4-methyl-4,5-dihydrobenzo[2,3]oxepino[4,5-d]thiazole-2-carboxylate was reacted with (R)-3-ethynyl-3-hydroxy-1-methylpyrrolidin-2-one to give a diasteromeric mixture of ethyl 8-fluoro-4-hydroxy-9-(((R)-3-hydroxy-1-methyl-2-oxopyrrolidin-3-yl)ethynyl)-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 after purification by prep HPLC.
