実験手順

To a crude sample of N-(6-chloro-2-phenylpyrimidin-4-yl)-2-{4-[(2E)-3-phenylprop-2-enyl]piperazin-1-yl}acetamide (22.54) (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 twice 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 (32 mg over 2 steps).
