Procedure

Using the same general procedure as step 3 of example 1, 3-[2-fluoro-4-(benzyloxycarbonyl) aminophenyl]thiazolidine (692 mg, 2.24 mmol) was treated sequentially with n-butyllitium (1.5 mL, 2.40 mmol) and (R)-(-)-glycidylbutyrate (0.33 mL, 2.33 mmol) to provide 500 mg (78%) of the title compound. Recystallization from methylene chloride/hexane provided an analytical sample with a melting point of 96°97° C.
