실험 절차

In the manner of Example VI, 7.6 g of 5-amino-4 -cyano-3-ethylisothiazole and 8.1 g of N-(dichloromethylene) -N,N-dimethylammonium chloride were allowed to react in 100 ml of dichloromethane. The volatile materials were evaporated under reduced pressure. The residue was recrystallized twice from cyclohexane to give 2.0 g of N'-(4-cyano-3-ethyl-5-isothiazolyl)-N,N-dimethylchloroformamidine, mp 95°-97°. The nmr spectrum was consistent with the assigned structure.
