반응 단계

A suspension of 0.23 g (0.0012 mol) of 5-chloromethyl-2-methyl-pyrimidin-4-ylamine in 10 ml of dimethylformamide was treated with 0.42 ml (0.0030 mol) of triethylamine and 0.29 g (0.0012 mol) of 7-benzyloxy-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 on silica gel with ethyl acetate as the eluent. 0.22 g (51%) of 5-(7-benzyloxy-3,4-dihydro-1H-isoquinolin-2-ylmethyl)-2-methyl-pyrimidin-4-ylamine was obtained as a colourless solid; m.p. 151°-153°.
