실험 절차

To a suspension of N-cyclopropyl-5-(diethylphosphonomethyl)-1-{4-[(ethylamino)carbonyl]phenyl}-1H-1,2,3-triazole-4-carboxamide (500 mg) obtained in Example 321b) in THF (20 ml) was added sodium hydride (50% oil dispersion, 80 mg) at 0° C., and the mixture was stirred at room temperature for 1 hr. A solution of 2-methyl-1,3-oxazole-4-carbaldehyde (148 mg) in THF (5 ml) was added to the obtained reaction mixture, and the mixture was stirred at room temperature overnight. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The extract was dried over magnesium sulfate and concentrated under reduced pressure, and the obtained residue was purified by silica gel column (ethyl acetate to ethyl acetate/methanol=4/1) to give the title compound as a white powder (380 mg).
