Reaction Steps

0.14 ml of triethylamine and 0.08 ml of methyl chloroformate were added to a solution of 250 mg of 4-(benzothiazol-2-ylmethoxy)aniline [prepared as described in Example 3(b)] in 5 ml of methylene chloride cooled in an ice-water bath and the resulting mixture was stirred at the same temperature for 50 minutes. The temperature of the reaction mixture was then elevated to room temperature and the mixture was stirred for a further 30 minutes. At the end of this time water was added to the reaction mixture and the resulting mixture was extracted with methylene chloride. The resulting extract was; washed with water and then dried over anhydrous sodium sulfate. The solvent was then removed by evaporation under reduced pressure to give a residue which was purified by column chromatography through silica gel using a 3:1 by volume mixture of hexane and ethyl acetate to give 243.1 mg (yield 79%) of the title compound as a solid having a melting point of 142°-144° C.
