Reaction Steps

5-(2-Ethylamino-ethyl)-3-methyl-4-oxo-1,4,5,6,7,8-hexahydro-pyrrolo[3,2-c]azepine-2-carbaldehyde 62j (45 mg, 0.118 mmol) was dissolved in 5 ml of ethanol under stirring, and added with 5-fluoro-1,3-dihydro-indol-2-one (16 mg, 0.106 mmol) and piperidine (0.15 ml, 1.49 mmol) to the solution. Upon completion of the addition, the reaction mixture was refluxed at 90° C. in an oil bath for 1 hour. After thin lay chromatography showed the disappearance of starting materials, the reaction mixture was concentrated under reduced pressure, added with a little ethanol, and filtered to obtain the title compound (Z)-5-(2-ethylamino-ethyl)-2-(5-fluoro-2-oxo-1,2-dihydro-indol-3-ylidenemethyl)-3-methyl-5,6,7,8-tetrahydro-1H-pyrrolo[3,2-c]azepin-4-one 62 (34 mg, yield 76%) as a yellow solid.
