반응 단계

By the procedure of Example 15, 2.59 g (0.019 mol) of N-isopropyl aniline was reacted neat with 2.32 g (0.0095 mol) of ethyl 2-chloro-4-trifluromethyl-5-oxazolecarboxylate at 140°-150° C. for 4 hours. The product mixture was slurried in ethyl ether, washed with 25% sulfuric acid and water, dried and concentrated. The residue was distilled and the distillate was recrystallized from methylcyclohexane to yield 0.7 g of a white-powder product (m.p.=66°-68° C.) identified in Table 1.
