Reaction Steps

4-(6-Methoxy-pyridin-3-yl)-1H-indole-2-carboxylic acid piperidin-4-ylamide (181), 150 mg, 0.43 mmol) is dissolved in 3 ml of ethanol under argon. After addition of sodium carbonate (182 mg, 1.7 mmol) and 2-bromo-ethanol (61 ul, 0.85 mmol), the reaction mixture is stirred at 80° C. for 13 h. The mixture is diluted with methylene chloride, filtrated and the filtrate is evaporated. Evaporation under reduced pressure gave 128 mg of crude product, which is further purified by Flash-chromatography (dichloro methane/methanol/25% ammonia (90:9:1). Yield: 90 mg (53%). MS (ESI): 395.2 [M+H]+.
