実験手順
Using the same general procedure as step 1, of Example 1, 4.092 g (45.90 mmol) thiazolidine was treated with 4.1 mL (37.03 mmol) 3,4-difluoronitrobenzene and 10.0 mL (57.41 mmol) N,N diisopropylethyl amine to provide 2.020 g (24%) of the title compound as an orange solid. Recystallization from methylene chloride/hexane provided an analytical sample with a melting point of 94°-95° C.
