Procedure
A solution of 15.1 g (0.22 mol) cyclopropylmethylamine in 50 ml tetrahydrofuran was added dropwise to a solution of 17 grams of diketene (0.20 mol) in 200 ml tetrahydrofuran at −5 to 0° C. After 1 h stirring at 0° C. no more starting material was detected by thin layer chromatography. The reaction mixture was evaporated and the residue is recrystallized from 100 ml of ethyl acetate. This gave 19.7 g (0.13 mol, 63% yield) of a white solid.
