Procedure

1-{(S)-2-[(5-Bromo-pyrimidin-2-ylamino)-methyl]-piperidin-1-yl}-1-[4-(4-fluoro-phenyl)-1-methyl-1H-pyrazol-3-yl]-methanone (0.35 g) in N-methylpyrrolidinone (10 ml) containing copper(I)cyanide (0.13 g) was heated to reflux for 5 h. The reaction mixture was diluted with water, filtered (Kieselguhr) and the filtrate extracted with ethyl acetate. The ethyl acetate phase was washed with water and brine, dried (MgSO4), filtered and solvent removed at reduced pressure. The residue was column chromatographed (silica gel; ethyl acetate:pentane 1:1→ethyl acetate eluant), the appropriate fractions combined and solvent removed at reduced pressure to give the title compound (0.019 g).
