실험 절차

A solution of 1, 4-dihydro-2-methoxy-6-methyl-4-(3-nitrophenyl) -5-pyrimidinecarboxylic acid, ethyl ester (3.19 g, 10.0 mmole; see Example 5A) and distilled triethylamine (4.18 ml, 30.0 mmol) in distilled dichloromethane (20 ml) in an ice bath under argon was treated dropwise via syringe with benzenesulfonyl chloride (1.53 ml, 12.0 mmol). The reaction was then stirred at room temperature overnight; and then over the weekend. The mixture was partitioned between ethyl acetate and water. The organic phase was washed with saturated sodium chloride and flash chromatographed to give the title compound as a light brown oil (2.94 g).
