실험 절차

A solution of 1,4-dihydro-2-methoxy-6-methyl-4-(3-nitrophenyl)-5-pyrimidinecarboxylic acid, 1-methylethyl ester (4.0 g, 12.0 mmol) in dry dimethylformamide (10 ml) under argon was treated with finely ground potassium carbonate (4.97 g, 36.0 mmoles), 3-phenylpropyl bromide (2.19 ml, 14.4 mmoles) and a catalytic amount of 18-crown-6. The resulting suspension was allowed to stir at room temperature for 72 hours, diluted with ether, filtered and the filtrate washed with water and brine. After drying over anhydrous magnesium sulfate, the solvent was evaporated. The residue was purified by flash chromatography (10-15% ethyl acetate in hexanes) to provide the desired product (3.29 g) as a yellow oil.
