87.5 °C

51.5 ml of a 50% aqueous solution of H3PO2 are added to a suspension of 109.5 g of diphenylmethanamine chloride in 750 ml of ethanol 90%, and then the reaction mixture is heated to 85-90° C. At that temperature, 58.4 ml of phenylacetaldehyde in 175 ml of ethanol are added over a period of 3 hours, and heating is continued for 3 more hours, followed by stirring for 16 hours at ambient temperature. The precipitate that is formed is filtered off, washed with cold ethanol and with diethyl ether and then dried, thereby allowing the expected product to be isolated.
