Reaction Steps

To 5-{2-[(Pyridin-4-ylmethyl)-carbamoyl]-pyridin-4-yl}-1H-indole-2-carboxylic acid ethyl ester (160 mg, 0.4 mmol) in ethanol (4 ml) is added aqueous sodium hydroxide (2N) and the mixture is stirred at 70° C. for 2 hours. The reaction is cooled, diluted with water (30 ml), acidified with aqueous HCl (3N) to pH 4-5, extracted with dichloromethane (50 ml). The combined organic layer is dried (sodium sulfate), filtered and evaporated in vacuo to give the title compound, 95 mg, 64%, LC/MS ESI m/z (M+H)+=273.8.
