Procedure

2.18 g. (0.015 mol) o-chlorobenzaldehyde is added dropwise to a solution of 3.5 g. (0.015 mol) aminomethyldiphenylphosphine in 150 ml. ethanol at ambient temperature. After evaporation of the solvent by heating to 50° C. under a slight vacuum, a clear yellow oil is obtained which is taken up hot in 50 ml. of a mixture of diisopropyl ether and ethanol (25/1 v/v). After cooling to 10° C., filtering and drying at 40° C. in vacuo, there are obtained 4.9 g. of crystals of the desired product; m.p. 89° C.
