Reaction Steps

In 100 ml of acetonitrile was dissolved 10 g (0.0567 mole) of 1-benzylpiperazine, and 11.7 g (0.085 mole) of potassium carbonate and 14.8 g (0.068 mole) of 4,6-dimethoxy-2-methylsulfonylpyrimidine were added thereto. The mixture was refluxed by heating for 5 hours. The mixture was cooled to room temperature and then filtered. The filtrate was concentrated under reduced pressure, and the residue was applied to silica gel column chromatography (the eluent used was a mixture of ethyl acetate:toluene=1:9) to obtain 17.6 g of 4-(4,6-dimethoxy-2-pyrimidinyl)-1-benzylpiperazine as colorless liquid.
