Diethyl Ether → 2-(Methyl-{5-[3-(4-trifluoromethyl-phenyl)-benzo[d]isothiazol-6-yl]-pent-4-ynyl}-amino)-ethanol

Participants

Reaction Steps

150 mg (0.34 mmol) Methanesulfonic acid 5-[3-(4-trifluoromethyl-phenyl)-benzo[d]isothiazol-6-yl]-pent-4-ynyl ester in 1.5 ml DMF w ere treated with 140 μl (1.7 mmol) N-allylmethylamine at 50° C. for 4 h. The solution was diluted with ether and water, the organic phase was washed with 0.5 M NaOH, and dried over Na2SO4. Column chromatography on silica gel gave 80 mg (56%) 2-(Methyl-{5-[3-(4-trifluoromethyl-phenyl)-benzo[d]isothiazol-6-yl]-pent-4-ynyl}-amino)-ethanol as light yellow, MS: 419(MH+).
