Reaction Steps

A suspension of 0.17 g (0.00088 mol) of 5-chloromethyl-2-methyl-pyrimidin-4-ylamine in 10 ml of dimethylformamide was treated with 0.30 ml (0.0021 mol) of triethylamine and 0.184 g (0.00088 mol) of 7-phenyl-1,2,3,4-tetrahydro-isoquinoline and the mixture was stirred at room temperature under argon for 18 hours. The solvent was distilled off in a high vacuum. The residue was partitioned between dichloromethane/water, extracted and dried over MgSO4. After removing the solvent the residue was chromatographed over silica gel with ethyl acetate as the eluent. 0.22 g (76%) of 2-methyl-5-(7-phenyl-3,4-dihydro-1H-isoquinolin-2-ylmethyl)-pyrimidin-4-ylamine was obtained as a light yellowish solid; m.p. 147°-149°.
