Reaction Steps

To a solution of 1-(3-methoxy-propyl)-1H-indole-6-carboxylic acid methyl ester (7 g, 28.5 mmol) in MeOH (50 mL) is added NaOH 2N (28.5 mL), and the mixture is stirred for 3 h. The solvent is concentrated and the remaining aqueous residue is acidified with HCl 1N and extracted twice with CH2Cl2. The combined organic extracts are dried over Na2SO4, filtered and concentrated to give title product. TLC, Rf (c-hexane/AcOEt 2:1)=0.25. MS (LC-MS): 232.0 [M+H]+, tR (HPLC, Macherey-Nagel Nucleosil C18 column, 10-100% CH3CN/H2O/5 min, 100% CH3CN/3 min, flow: 1.5 ml/min): 5.04 min.
