Reaction Steps

A mixture of ethyl 2,5-dimethyl-1-phenethyl-1H-indole-3-carboxylate (500 mg) and NaOH (500 mg) in ethanol (15 mL) was heated at 100° C. for 3 h at which point the reaction was found complete by TLC and LC-MS. The reaction mixture was acidified to pH 4-5 by adding ethanolic HCl and evaporated under reduced pressure. The residue (1 g), that also contained NaCl generated during NaOH neutralization, was carried forward to next reaction without any purification.
