Versuchsvorschrift
By the procedure of Example 39, a stirred mixture of 10 ml acetonitrile, 2.28 g (38.6 mmol) of iso-propylamine, and 5 g (19.3 mmol) of ethyl 2-chloro-4-trifluoromethyl-5-thiazolecarboxylate (prepared as described in U.S. Pat. No. 4,199,506), was heated at reflux for 16 hours. The product was separated and then recrystallized in hexane to yield 2.30 g of a beige solid product (m.p.=94°-97° C.) identified in Table 1.
