Procedure

To a stirred solution of 2,2-diphenylethylamine (100.0 g, 0.5 m) and triethylamine (123.0 g, 1.2 m) in chloroform (2 liters) maintained under nitrogen at ambient temperature was added dropwise chloroacetylchloride (124.2 g, 1.1 m) and the mixture stirred for 2 hours. Thin layer chromatography (TLC) analysis showed the reaction to be complete. The mixture was transferred to a separatory funnel and washed with 10% HCl (3 ×1 liter) and water (1 liter) and the organic phase dried over MgSO4. The solvent was evaporated to a dark oil which was treated with cyclohexane (1 liter) and, upon standing, a solid crystallized which was collected by filtration, washed with cyclohexane and air dried to give 122.0 g of N-chloroacetyl-1,1-diphenylethylamine as a tan solid, m.p. 73°-74°.
