Conditions

Temperature: 110 °C

Procedure

To (trans)-4-(1-(3-methoxy-4-(4-methoxy-1-methyl-1H-indole-2-carboxamido)phenyl)-8-methylimidazo[1,5-a]pyrazin-3-yl)cyclohexyl acetate (0.034 mmol, 20 mg) in acetonitrile (0.5 ml) and water (0.5 ml) was added potassium hydroxide (0.172 mmol, 9.65 mg) and the mixture was stirred at 110° C. After one hour the reaction mixture was neutralized with 2N hydrochloric acid, extracted with dichloromethane three times, the combined organic layers were dried (sodium sulfate) and concentrated in vacuo. The crude product was purified using column chromatography (silica gel; gradient dichloromethane to dichloromethane/methanol 25/1) to yield the title compound (7 mg).
