Reaction Steps
6.36 g (50 moles) of 3-benzyl-2-cyanimino-thiazolidine are boiled with 80 ml of a 10% hydrochloric acid for 10 minutes. A clear solution is obtained, which is cooled down and alkalized with a 25% aqueous ammonium hydroxide solution to yield 5.65 g of 3-benzyl-2-carbamoylimino-thiazolidine, melting at 143° to 145° C. After crystallization from ethanol the melting point is raised to 148° C.
