実験手順
By the procedure of Example 4, 6.13 g (60 mmol) of n-propyl urea was reacted with 10.9 g (50 mmol) of ethyl 2-chloro-4,4,4-trifluoroacetoacetate at 140°-150° C. for 18 hours. The product was separated and then recrystallized from n-heptane to yield 2.3 g of a yellow powder product (m.p.=33°-34° C.) identified in Table I.
