実験手順
A mixture of 3-(2-amino-ethyl)-1H-indol-5-ol hydrochloride (0.5 g), trifluoroacetaldehyde ethyl hemiacetal (0.35 mL), acetic acid (0.32 mL) and ethanol (22.5 mL) was heated at reflux for 16 h. The solvent and excess reagents were evaporated to dryness under vacuum. The residue was washed with diethyl ether to afford 1-trifluoromethyl-2,3,4,9-tetrahydro-1H-β-carbolin-6-ol hydrochloride (0.5 g).
