Procedure

Acrylonitrile (10 mL of 1.52 M in 1,4-dioxane, 30.4 mmol) was added to methyl 2-bromo-3-cyclohexyl-1H-indole-6-carboxylate (840 mg, 2.5 mmol) in a microwave vial. The vial was sealed and Triton® B (500 μL 1.1 μmol) was added via syringe. The vial was heated in a microwave apparatus for 1 hr at 100° C. The solution was cooled and poured to precipitate the crude product. The granular solid was collected, washed with water and dried. Recrystallization from ethanol gave the product as a colorless solid (696 mg, 74%).
