YieldReaction ConditionsOperation in experiment
With bromine; In acetic acid; 2-Amino-4,6-dichlorobenzothiazole 197 g (1.23 mol) of bromine were slowly added dropwise, while cooling with ice, to a solution of 200 g (1.23 mol) of 2,4-dichloroaniline and 200 g (2.46 mol) of sodium thiocyanate in 1.5 1 of glacial acetic acid. Stirring was carried out for 16 hours at about 20 C., after which the solid was separated off and washed with 10% strength sodium hydroxide solution and water. Yield: 205 g. 1 H-NMR (270 MHz; in d6 -dimethyl sulfoxide): delta [ppm]=7.39 (d,1H), 7.80 (d,1H), 8.00 (s,2H).

Stirring was carried out for 16 hours, after which the reaction mixture was acidified with 10% strength hydrochloric acid. The product was then extracted with methyl tert-butyl ether. The organic phase was washed with water, dried over magnesium sulfate and finally evaporated down. Purification of the crude product was carried out by means of column chromatography over silica gel (eluent: 1:1 cyclohexane/ethyl acetate). Yield: 9.1 g. 1 H-NMR (250 MHz; in d6 -dimethyl sulfoxide): delta [ppm]=7.78 (d,1H), 8.24 (d,1H).
