Reaction Steps

3-methyl-4-oxo-5-(2-pyrrolidin-1-yl-ethyl)-1,4,5,6,7,8-hexahydro-pyrrolo[3,2-c]azepine-2-carbaldehyde 28c (75 mg, 0.262 mmol) and 5-(2,6-dichloro-phenylmethanesulfonyl)-1,3-dihydro-indol-2-one 64c (84 mg, 0.236 mmol) were dissolved in 2.5 ml of ethanol, and added with 42 μl of piperidine to the solution at room temperature. Upon completion of the addition, the reaction mixture was heated to reflux for 3 hours. After thin lay chromatography showed the disappearance of starting materials, the reaction mixture was naturally cooled to room temperature, and filtered. The filter cake was washed with anhydrous ethanol (3 ml×2) and dried to obtain the title compound (Z)-2-((5-(2,6-dichlorobenzylsulfonyl)-2-oxoindolin-3-yl idene)methyl)-3-methyl-5-(2-(pyrrolidin-1-yl)ethyl)-5,6,7,8-tetrahydropyrrolo[3,2-c]azepin-4(1H)-one 66 (117 mg, yield 79.6%) as an orange solid.
