[Chemical 13] 2- (2-Ethyl-1H-imidazol-1-yl) benzoic acid (260 mg) was added to a dichloromethane solution (10 ml),
After adding 1 drop of N, N-dimethylformamide, 1.5 equivalents of oxalyl chloride was added dropwise under ice cooling, and the mixture was stirred under ice cooling for 30 minutes and room temperature for 30 minutes. After distilling off the solvent, 10 ml of dichloromethane was added again to give 1- (4-aminobenzoyl) -5- (3-pyridylmethyl) -2,3,3.
290 mg of 4,5-tetrahydro-1H-1,5-benzodiazepine and 1 equivalent of triethylamine were added dropwise to 10 ml of a dichloromethane solution under ice cooling, and the mixture was stirred for 1 hour. The reaction solution was added to ice water and then extracted with dichloromethane. The dichloromethane layer was washed with water and saturated brine, dried over anhydrous magnesium sulfate, and the solvent was evaporated.
