実験手順

80 mg (0.25 mmol) {3-[3-(4-Chloro-phenyl)-benzo[d]isothiazol-6-yl]-prop-2-ynyl}-dimethyl-amine in 2 ml EtOH were hydrogenated in the presence of 20 mg PtO2. H2O , purification by flash silica gel column (CH2Cl2/MeOH 9:1) yielded 43 mg (53%) {3-[3-(4-Chloro-phenyl)-benzo[d]isothiazol-6-yl]-propyl}-dimethyl-amine as a colorless oil, MS: 331 (MH+, 1Cl).
