PROCEDURE

实验过程

A mixture of 4-trifluoromethylnicotinic acid (100 mg, 0.523 mmol), (4-amino-2-phenylbenzoyl)methionine methyl ester hydrochloride (206 mg, 0.52 mmol), prepared as in Example 192B, 3-hydroxy1,2,3-benzotriazin-4(3H)-one (120 mg, 0.628 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide (125 mg, 0.628 mmol) in THF (5 mL) was stirred 15 hours. The reaction mixture was diluted with ethyl acetate , washed with water and brine, dried over anhydrous magnesium sulfate, filtered and concentrated in vacuo. The residue was purified by column chromatography (50% ethyl acetate-hexane) to give the title compound (157 mg, 57%).
