実験手順

A suspension of N-{[3′-({[(4-oxo-3,4-dihydroquinazolin-2-yl)carbonyl]amino}methyl)biphenyl-4-yl]sulfonyl}valine obtained in Example 77 (0.080 g, 0.150 mmol), O-(trimethylsilyl)hydroxylamine (0.055 mL, 0.449 mmol), 1-[3-(dimethylamino)propyl]-3-ethyl-carbodiimide hydrochloride (0.086 g, 0.449 mmol) and 1-hydroxybenzotriazole (0.061 g, 0.449 mmol) in DMF (5 mL) was stirred at room temperature for 12 hr. The reaction mixture was diluted with ethyl acetate, and washed successively with 0.05N hydrochloric acid, aqueous sodium hydrogencarbonate solution, water and saturated brine, and dried over sodium sulfate. The solvent was evaporated under reduced pressure, and the residue was crystallized from methanol-diethyl ether to give the title compound as a white powder (0.058 g, 71%).
