Procedure

10% Palladium-on-carbon (0.3 g) was added to a solution of 2,2-diphenyl-5-[N-(4-cyanophenethyl)-N-methylamino]pentanamide (0.3 g--see Example 13) in 5% formic acid in methanol (21 ml). The mixture was stirred at room temperature under nitrogen for 1 hour, then filtered and the filtrate concentrated in vacuo to give a gum which was purified by column chromatography on silica eluting with dichloromethane containing methanol (2% up to 10%). The product-containing fractions were combined and concentrated in vacuo to give an oil which crystallised on standing. The solid was triturated with ether to give the title compound as buff crystals, yield 0.1 g, m.p. 139°-142°.
