Procedure

To a solution of 258 mg of the compound of Example 10, 71 mg of HOBt and 101 mg of EDCI.HCl in 5 ml of THF, and 0.5 ml of 2.0 M methylamine-THF solution were added, and the mixture was stirred at room temperature overnight. The reaction solution was mixed with saturated NaHCO3 aq. and extracted with chloroform. The organic layer was dried over anhydrous magnesium sulfate. The crude product obtained by evaporation of the solvent was purified by silica gel column chromatography (chloroform-MeOH (30:1)). The residue obtained by concentration under reduced pressure was crystallized from a 2-propanol-hexane solvent mixture to obtain 51 mg of (2Z)-2-{1-[2-chloro-4-(3-methyl-1H-pyrazol-1-yl)benzoyl]-4,4-difluoro-1,2,3,4-tetrahydro-5H-1-benzazepin-5-ylidene}-N-[2-(methylamino)-2-oxoethyl]acetamide.
