Reaction Steps

Heating a suspension of ethyl 3-methyl-2-(3-pyridyl)indole-5-propionate hydrochloride in 450 ml of 2N HCl at reflux temperature for 2 hours, cooling and collecting the resulting solid gave 3-methyl-2-(3-pyridyl)-indole-5-propionic acid hydrochloride, m.p. 290°. Similar hydrolysis of ethyl 3-methyl-2-(4-pyridyl)indole-5-propionate yielded 3-methyl-2-(4-pyridyl)indole-5-propionic acid hydrochloride, melting above 305°.
