실험 절차

A solution of the resulting 2-(5-phenyl-[1,2,4]oxadiazol-3-yl)-morpholine hydrochloride (intermediate 28) in tetrahydrofuran (6.0 ml) was added with 2-chloro-3-methyl-6-(pyrimidine-4-yl)pyrimidin-4-one (intermediate 1 260 mg, 2.34 mmol) and triethylamine (1.81 ml, 13.0 mmol), and the reaction mixture was stirred at room temperature for 2 hours. The solution was partitioned between water and chloroform, and the organic layer was washed with water and brine, dried over magnesium sulfate, and concentrated in vacuo. The resulting residue was purified by column chromatography on silica gel (eluent; 5% methanol in chloroform) to afford 1-methyl-2-[2-(5-phenyl-[1,2,4]oxadiazol-3-yl)-morpholin-4-yl]-1H-[4,4′]bipyrimidinyl-6-one (compound 2 in Table 1, 749 mg, 64%, 2 steps) as solid
