Reaction Steps

To a solution of 100 mg (0.46 mmol) of 7-cyanomethyl-1H-indole-2-carboxylic acid ethyl ester (the preparation of which is described in Chem. Pharm. Bull. 1996, 44, 55) in THF/EtOH/H2O (5 ml) at RT was added 50 mg of LiOH.H2O. The reaction mixture was stirred at 45° C. for one hour and then acidified with aqueous HCl 1M. The product was extracted with EtOAc and concentrated under vacuo to afford 80 mg (85%) of 7-Cyanomethyl-1H-indole-2-carboxylic acid as a white solid. ES-MS m/e (%): 199.6(M−H+).
