Procedure

HCl is passed for 2 hours into a solution of 3.88 g of 2-[4-(5-carboxy-3-indolyl)butyl]-1,2,3,4-tetrahydrobenzofuro[2,3-c]pyridine in 50 ml of absolute ethanol. The mixture is then allowed to stand at 20° for 48 hours, the usual working up is carried out, and 2-[4-(5-ethoxycarbonyl-3-indolyl)butyl]-1,2,3,4-tetrahydrobenzofuro[2,3-c]pyridine is obtained.
