Dimethyl N-cyanodithioiminocarbonate → HCID 178487240, compound

Participants

Reaction Steps

To a stirred solution of 17.8 g of 7-methoxy-1,2,3,4-tetrahydro-1-naphthylamine hydrochloride in 150 ml of ethanol at 0° C. was added 15.5 g of dimethyl cyanodithioiminocarbonate over a period of 30 minutes. The mixture was then allowed to remain at room temperature for 2 days after which the reaction mixture was cooled and the resulting crystals were collected by filtration. Concentration of the mother liquor gave a second crop of crystals. The combined product was recrystallized from ethanol to give 19.9 g of N'-cyano-N-(7-methoxy-1,2,3,4-tetrahydro-1-naphthyl)-S-methylisothiourea as colorless plates, mp 131°-132° C.
