Versuchsvorschrift

A solution of 30 g (170 mmol) of 4-(methylmercapto)aniline dissolved in 83 ml of acetic acid and 165 ml of water was heated to 40° C. Once warmed to 40° C. a solution of sodium cyanate (22.2 g; 340 mmol) in 150 ml of water was slowly added. The resulting suspension was stirred for 15 minutes and then allowed to sit for 2 hours. Filtration of the suspension provided 29.98 g of title compound. m.p. 155°-159° C.
