1.3 g (0.0057 mol) of 2,2-dichloro-1-methyl-3-phenylcyclopropane carbaldehyde were dissolved in 16 ml of anhydrous benzene. The resulting benzene solution was admixed with 0.5 g of anhydrous sodium sulfate, and stirred. To the benzene solution was dropwise added a solution of 2.0 g (0.027 mol) of t-butylamine in 4 ml of the same solvent over 15 minutes. After further stirring for 94 hours, the reaction mixture was filtered to remove the inorganic substances therefrom. Then the benzene and the t-butylamine were distilled off under a reduced pressure to obtain 1.3 g of 2,2-dichloro-1-methyl-3-phenylcyclopropane-methylidene-t-butylamine as an oily substance with light yellow color. Yield: 81%.
