실험 절차

A solution of methyl[4-chloro-6-methyl-2-(4-nitrobenzyl)pyrimidin-5-yl]acetate (0.45 g, 1.3 mmol) and pyrrolidine (0.13 mL, 1.6 mmol) in DMF (10 mL) at room temperature was treated with triethylamine (0.22 mL, 1.6 mmol) and the resulting mixture was stirred at 85° C. for 13 hours. After cooling to room temperature, the reaction mixture was poured into water and extracted with EtOAc. The combined organic extracts was washed with saturated NaHCO3 and brine, dried over anhydrous MgSO4, filtered, and concentrated in vacuo. The crude product thus obtained was chromatographed over silica gel eluting with 50% EtOAc in CH2Cl2 to give methyl[4-methyl-2-(4-nitrobenzyl)-6-pyrrolidin-1-ylpyrimidin-5-yl]acetate (0.40 g, 80% yield) as a white powder.
