A boiling solution of 7.5 g. (0.02 mole) of 3-(3-carboxy-4-hydroxyphenyl)-4,5-dihydro-2-phenylbenz[e]indole and 200 ml. of ethanol was saturated with hydrogen chloride, then heated under reflux for 26 hours and cooled. The solid which separated was collected and recrystallized from ethanol to provide 4.1 g. (51%) of off-white crystals, m.p. 134°-135°.
