Production method: the intermediate N-chloromethyl N-phenylcarbamyl chloride was prepared by the reaction of N-methylaniline with phosgene and chlorine. In the presence of acid, tert-butanol reacts with ammonium thiocyanate, then translocation to obtain tert-butyl isocyanate, and then reacts with isopropylamine to produce 1-isopropyl - 3-tert-butylthiourea. The latter reacts with the N-chloromethyl-n-phenylcarbamyl chloride in the presence of a base to produce thiazinone. The original drug thiazinone is a grayish white or light yellow crystal powder. The active ingredient content of grade 1 product is ≥95.0%, and the qualified product is ≥90.0%. Raw material consumption quota: tert-butanol (85%) 600kg/t, n-methylaniline (99%) 800kg/t, isopropylamine (98%) 350kg/t.
