Chloroacetyl chloride → HCID 18932280, compound

Participants

Reaction Steps

0.24 ml of triethylamine and 0.17 ml of chloroacetyl chloride were added to a solution of 300 mg of 4-(benzothiazol-2-ylmethoxy)aniline [prepared as described in step (b) above] in 6 ml of methylene chloride cooled in an ice-water bath, and the resulting mixture was stirred for 1 hour. After this time, a saturated aqueous ammonium chloride solution was added to the reaction mixture and the resulting mixture was extracted with methylene chloride. The resulting extract was washed with water, dried over anhydrous sodium sulfate and the solvent was then removed by evaporation under reduced pressure. The resulting residue was recrystallized from a mixed solvent of methylene chloride and hexane to obtain 259.4 mg (yield 65.5%) of the title compound as a solid having a melting point of 196° to 197° C.
