N-辛基脲

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: By the procedure of Example 4, 5.16 g (30 mmol) of n-octyl urea was reacted with 5.4 g (25 mmol) of ethyl 2-chloro-4,4,4-trifluoroacetoacetate at 140°-150° C. for 18 hours. The product was separated and then recrystallized from petroleum ether to yield 1.5 g of a white powder product (m.p.=36°-37° C.) identified in Table I. The product was separated recrystallized from petroleum ether
