Reaction Steps

Ethylendiamine tosylate (929 mg, 4.0 mmol) and 5-chloro-3-cyano-2-(3-fluorophenyl)-1H-indole (0.27 g, 1.0 mmol) were thoroughly mixed in a mortar and heated with melting at 320° C. for 10 min. After cooling it was stirred with a small amount of water, and the mixture was brought to pH9 with 2N sodium hydroxide. The precipitate was collected by filtration, washed with water, and dried in vacuo. The title imidazoline was isolated by chromatography on silica gel with dichloromethane/10% ethanolic ammonia 9:1 and recrystallized from methanol.
