실험 절차

Preparation of the title compound was carried out according to General Method 8. p-Tolylhydrazine hydrochloride (10 g, 63 mmol), 2-phenyl ethyl bromide (11.6 g, 63 mmol), triethyl amine (19.4 g, 189 mmol) and 2,2,2-trichloroethyl 4-oxopiperidine-1-carboxylate (452 mg, 2 mmol) were taken in ethanol (10 ml) at 90° C. for 3 h to obtain 200 mg of 2,2,2-trichloroethyl 3,4-dihydro-8-methyl-5-phenethyl-1H-pyrido[4,3-b]indole-2(5H)-carboxylate after purification on silica gel (230-400 mesh) chromatography eluting with methanol-dichloromethane gradient.
