Procedure

A mixture of 0.72 g (2.9 mmol) N-cyanomethyl-3,3-diphenylpropylamine (from step 1), 0.49 g (3.4 mmol) iodomethane and 1.6 g potassium carbonate in 5 ml acetonitrile was stirred at room temperature for 16 hours. The reaction mixture was diluted with dichloromethane, washed with water, the solvent evaporated, and the residue chromatographed on silica gel column with 20% ethyl acetate in hexanes to give 0.33 g (yield 43%) N-methyl-N-cyanomethyl-3,3-diphenylpropylamine as an oil which solidified on standing. 1H NMR ((CDCl3, 300 MHz) 7.30–7.10 (m, 10 H), 4.02 (t, 1 H), 3.47 (s, 3 H), 2.38 (t, 2 H), 2.32 (s, 3H), 2.19 (dt, 2H);
