Procedure

To a solution of 2,3-dihydro-5-hydroxy-2,6,7-trimethyl-4-(2-methyl-2-propen-1-yl)-1H-indole-1 carbaldehyde (0.26 g, 1.0 mmol) in ethanol (3 mL) was added concentrated hydrochloric acid (0.5 mL), and the mixture was heated to reflux for 1 hour. The reaction mixture was treated with active carbon, filtered, and concentrated under reducer pressure. The residue was recrystallized from ethanol-diethyl ether to obtain 0.14 g of the title compound.
