Reaktionsschritte

In the manner of Example VI, 9.1 g of 5-amino-3-tert-butyl- 4-cyanoisothiazole and 9.8 g of N-(dichloromethylene)-N,N-dimethylammonium chloride were allowed to react in 50 ml of dichloromethane. The volatile materials were evaporated under reduced pressure. The residue was recrystallized from hexane to give 9.2 g of N'-(3-tert-butyl-4 -cyano-5-isothiazolyl)-N,N-dimethylchloroformamidine, mp 94°-100°. The ir and nmr spectra were consistent with the assigned structures.
