Reaction Steps

To the saturated solution of 5-Bromo-1-(4-fluorobenzenesulfonyl)-3-(4-methylpiperazin-1-ylmethyl)-1H-indole (2.3 g) in diethyl ether, the saturated solution of maleic acid in diethyl ether was added slowly under cooling and stirring. The mass was stirred till solid separates out. The crystalline solid was isolated by filtration, washed with hexane, ethyl acetate and dried quickly under vacuum over phosphorous pentoxide. IR spectra (cm−1): 1157, 1182, 1384, 1572, 1622, 1692; Mass (m/z): 466 (M+H)+, 468 (M+H)+.
