実験手順
N-methyl-N'-o-fluorophenyl urea (16.8 g, 0.1 mol) was combined with 22.5 g (0.15 mol) chloral and 18.0 g (0.15 mol) thionyl chloride. After several minutes, an exothermicity was noted and the reaction mixture became a homogenous yellow oil. After 5 minutes more, a precipitate began to form. After 1 1/2 hours, a 3:1 mixture of diethyl ether:petroleum ether was added and the product was collected of a filter and dried. The solid, which weighed 25 g, melted at 130°-141° C and analyzed as follows: %Cl, calc. 35.7, found 37.3; %N, calc. 9.5, found 9.5.
