Reaction Steps

1.19 g (10.1 mmoles) of thionyl chloride was added, at room temperature, to a solution of 0.42 g (2.02 mmoles) of (4-methoxy-6-trifluoromethylpyrimidin-5-yl)-methanol. The mixture was stirred for 3 hours to give rise to a reaction. After confirmation of the completion of the reaction, the reaction mixture was subjected to vacuum distillation to remove the solvent contained therein, to obtain 0.45 g (yield: quantitative) of 5-chloromethyl-4-methoxy-6-trifluoromethylpyrimidine.
