실험 절차

A mixture of 4-[7-(3,4-dichloro-phenylsulfanyl)-isoquinolin-1-yl]-piperazine-1-carboxylic acid tert-butyl ester (230 mg, 0.47 mmol), H2O2 (30% in water, 0.5 mL), trifluoroacetic acid (1.5 mL) was heated at 50° C., 2 h. The reaction was continued overnight at 35° C. A water solution of NaOH (1N) was added (pH=14), ethyl acetate was added and the organic phase was separated, dried (MgSO4), filtered. The filtrated was concentrated and the residue was purified by flash column chromatography (SiO2, dichloromethane:methanol 9:1) The free base was converted into hydrochloride by treatment with HCl in diethyl ether to obtained 45 mg of the title compound. 1H NMR (CH3OH-d4) δ 8.75-8.85 (m, 1H), 8.10-8.30 (m, 4H), 7.90-8.00 (m, 1H), 7.75-7.85 (m, 1H), 7.50-7.60 (m, 1H), 3.85-3.90 (m, 4H), 3.50-3.70 (m, 4H).
