To a solution of 22.2 g. of methyl magnesium chloride in ether is added 10.5 g. of 4-pyrimidinecarbonitrile in tetrahydrofuran. The resulting mixture is heated at reflux for 24 hours, then poured onto ice. To the mixture is added 75 ml. of 25 percent sulfuric acid. The solution is then made basic with 10 percent aqueous sodium carbonate solution and extracted with ether. The extracts are dried and concentrated to give methyl 4-pyrimidyl ketone.
