Reaction Steps

A suspension of 7.0 g (0.020 mol) of 5-bromomethyl-2-propyl-pyrimidin-4-ylamine dihydrobromide, 3.85 g (0.020 mol) of (2-methoxy-phenyl)-piperazine and 6 g (0.043 mol) of dry potassium carbonate in 75 ml of dimethylformamide was dissolved at room temperature for 4 hours. The reaction mixture was suction filtered, the filter cake was washed with ethyl acetate and ethanol, the filtrate was completely freed from the solvents and the residue was chromatographed over silica gel with ethyl acetate as the eluent and recrystallized from hot ethyl acetate. 1.3 g (21%) of 5-[4-(2-methoxy-phenyl)-piperazin-1-ylmethyl]-2-propyl-pyrimidin-4-ylamine were obtained as yellowish crystals, m.p. 130°.
