実験手順

75 mg (0.18 mmol) 6-(2-Bromo-ethoxy)-3-(4-bromo-phenyl)-benzo[d]isothiazole in 2.5 ml DMA were treated with 98 μl (0.54 mmol, 3 eq) 5.6 M N,N-dimethylamine in ethanol for 35 h at RT. The solution was diluted with ether and a saturated aqueous solution of NaHCO3. The inorganic phase was extracted with ether, the combined organic phases were washed with brine and dried over Na2SO4. Column chromatography on silica gel with CH2Cl2:MeOH 8:1 yielded 63 mg (92%) [2-[3-(4-Bromo-phenyl)-benzo[d]isothiazol-6-yloxy]-ethyl]-dimethyl-amine as colorless oil, MS: 377(MH+, 1Br).
