Participants

Reaction Steps

6.3 g (0.03 mol) of 5-methyl-7-nitro-benzothiazolone and 3.3 g (0.03 mol) of triethylamine are dissolved in 150 ml of acetone. 2.35 g (0.03 mol) of acetyl chloride are allowed to run in slowly dropwise, with stirring, at an internal temperature of 5°-10° C. The reaction mixture is stirred at room temperature for a further 3 hours and then poured onto ice. 6.3 g (83 % of theory) of 3-acetyl-5-methyl-7-nitro-benzothiazolone are obtained in the form of creamcolored flakes of melting point 141° C.
