Procedure

Triethylamine (1.89 g, 18.68 mmol) was added to a solution of ethyl 4-chloro-6-ethylpyrimidine-5-carboxylate (2.00 g, 9.32 mmol) in toluene (50 ml). The mixture was stirred at room temperature. Then, 4-butoxyphenethylamine (2.16 g, 11.18 mmol) was added. After stirring for 18 hours, water (40 ml) was added to the reaction mixture. The mixture was extracted with ethyl acetate and dried over magnesium sulfate. After evaporation of the solvent, the residue was purified by column chromatography on silica gel eluting with n-hexane/ethyl acetate (=8/2) to give the desired ethyl 4-(2-(4-butoxyphenyl)ethylamino)-6-ethylpyrimidine-5-carboxylate (2.00 g, 58%).
