実験手順

To a solution of 2-isopropylamino-6-methyl-pyrimidine-4-carboxylic acid methoxy-methyl-amide (2.39 g, 10.0 mmol) in THF (50 mL), methyl magnesium bromide (7.0 mL of a 3 M solution in ether, 20.1 mmol) is added dropwise at 5° C. The mixture is stirred at 5° C. for 1.5 h. The reaction is quenched by adding NH4Cl. The mixture is diluted with EtOAc (75 mL), washed with sat. aq. NaHCO3, dried over Na2SO4, filtered and concentrated to give 1-(2-isopropylamino-6-methyl-pyrimidin-4-yl)-ethanone (1.71 g) as a yellow solid. LC-MS: tR=0.75 min, [M+H]+=194.01; 1H NMR (CDCl3): δ 1.29 (d, J=6.5 Hz, 6H), 2.41 (s, 3H), 2.62 (s, 3H), 4.22 (m, 1H), 5.02 (m, 1H), 6.97 (s, 1H).
