Procedure

(S)-5-(2-Hydroxy-3-morpholin-4-yl-propyl)-3-methyl-4-oxo-1,4,5,6,7,8-hexa hydro-pyrrolo[3,2-c]azepine-2-carbaldehyde 78f (40 mg, 0.12 mmol) and 4-bromo-1,3-dihydro-indol-2-one (25 mg, 0.12 mmol) were dissolved in 1.5 ml of ethanol, and added with 6 μl of piperidine to the solution at room temperature. Upon completion of the addition, the reaction mixture was stirred at 45° C. for 16 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 (1 ml×2) and dried to obtain the title compound (S,Z)-2-(4-bromo-2-oxoindolin-3-ylidene)methyl)-5-(2-hydroxy-3-morpholinoprop yl)-3-methyl-5,6,7,8-tetrahydropyrrolo[3,2-c]azepin-4(1H)-one 81 (34 mg, yield 54%) as a yellow solid.
