Procedure

To a crude sample of N-(6-chloro-2-phenylpyrimidin-4-yl)-2-(4-benzylpiperidin-1-yl)acetamide (22.55) (0.75 g in 60 ml DMSO) were added glycinamide hydrochloride (1.85 g in 10 ml DMSO) and N,N-diisopropylethylamine (2.96 ml) and the mixture heated to 100° C. for 16 hrs. The solvent was then removed in vacuo and the residue purified by flash chromatography on silica gel using mixtures of dichloromethane and methanol (97:3, 95:5 then 93:7 v/v/v). Further purification by recrystallization from methanol furnished the title compound (326 mg over 2 steps).
