Reaction Steps

25.3 g (0.1 mol) of 2-carbamyl-5-nitro-7-methylbenzothiazolone-N-oxide are suspended in 150 ml of anhydrous toluene. 16.8 g (0.11 mol) of phosphorus oxychloride are added dropwise to this suspension, with stirring, at an internal temperature of 100° C. and the reaction mixture is heated under reflux for a further 4 hours and allowed to cool. 15.8 g (75 % of theory) of 5-nitro-7-methyl-benzothiazolone of melting point >250° C. are obtained.
