実験手順

A mixture of benzophenone imine (25 g, 0.138 mol, Aldrich) and aminoacetonitrile hydrochloride (25 g, 0.270 mol, Lancaster) in dichloromethane (1000 mL) was stirred in a 2 L Erlenmeyer flask under nitrogen at room temperature for five days. The reaction mixture was filtered to remove the precipitated ammonium chloride and the filtrate was evaporated to dryness in vacuo. The resulting residue was dissolved in ether (400 mL) and washed with water (200 mL) and brine. After drying over magnesium sulfate, the solution was evaporated to give (benzhydrylideneamino)-acetonitrile (47.89 g).
