반응 단계

A solution of 23.6 g (0.24 mol) of cyclohexylamine in 50 ml tetrahydrofuran was added dropwise to a solution of 20 g of diketene (0.24 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 30.0 g (0.16 mol, 69% yield) of a white solid.
