Yield:7716-66-7 92.7%
Reaction Conditions:
in chlorobenzene;paraffin oil
Steps:
6 Example 6
Example 6 Example 5 was repeated, except that 4 kg of 93% by weight pure benzisothiazolone and 90 g of 1,3-dimethylimidazolidinone in 5 l of chlorobenzene were phosgenated. To obtain the reaction product, 200 ml of high boiling paraffin oil were added prior to the vacuum distillation, and a Vigreux column of 20 cm in length was used. 3-Chlorobenzisothiazole of a purity of 99.4% by weight was obtained in a yield of 92.7% of theory.
