実験手順

By the procedure of Example 4, 7.68 g (60 mmol) of cyclopentyl 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 methylcyclohexane to yield 5.0 g of a white solid product (m.p.=41°-42° C.) identified in Table I.

後処理

  1. customThe product was separated
  2. customrecrystallized from methylcyclohexane
