実験手順
A mixture of 4-(2-fluoropropan-2-yl)pyrimidine-5-carbonitrile (1.0 equiv.) and Raney-nickel in THF (0.5 M) was degassed under vacuum. The resulting mixture was hydrogenated under a fully-inflated balloon at room temperature overnight. The mixture was filtered through a pad of celite and the cake was rinsed with MeOH. The filtrate was concentrated and further dried to give a brown oil, which was purified by silica gel column chromatography (0-20% MeOH in ethyl acetate, 50 g column) to give (30% yield) of pale yellow oil as a 3:2 mixture of the above two products. MS (ESI) m/z 152.0 [M+1]+. MS (ESI) m/z 170.0 [M+1]+.
