HCID 10602784[(Z)-1-[4-(2-Biphenylylcarbonylamino)benzoyl]-4,4-difluoro-2,3,4,5-tetrahydro-1H-1-benzazepine-5-ylidene]acetic acid methyl esterYield 95.4%

Procedure

Using 396 mg of o-phenylbenzoic acid, 0.290 ml of oxalyl chloride and 620 mg of methyl (Z)-[1-(4-aminobenzoyl)4,4-difluoro-2,3,4,5-tetrahydro-1H-1-benzazepin-5ylidene]acetate, a similar procedure as in Reference Example 8 was repeated to obtain 878 mg of methyl (Z)-[4,4-difluoro-1-[4-(2-phenylbenzoylamino)benzoyl]-2,3,4,5-tetrahydro-1H-1-benzazepin-5-ylidene]acetate.
