실험 절차
A solution of 1.03 g of ethyl 6,7-dihydro-9-hydroxypyrido[1,2-a]indole-8-carboxylate in 20 ml of ethanol, 10 ml of water and 10 ml of concentrated hydrochloric acid was heated at 80° C. for 3 hours. The solvents were evaporated to give 740 mg of 7,8-dihydropyrido[1,2-a]indol-9(6H)-one of melting point 138°-140° C.
