Procedure

10 g of anhydrous benzyl alcohol are placed in 150 ml of absolute benzene and 7.4 g of sulfuryl diisocyanate are added dropwise accompanied by stirring. The exothermic reaction which takes place leads to a rise in the temperature to 45° C. and shortly after the start a precipitate is formed. Following the temperature drop, stirring is continued for 1 hour at ambient temperature. The resulting precipitate is suction filtered and dried at 60° C. giving a yield of 18.06 g of colorless crystals (99.2% of theory), m.p. 139°-141° C., which can be recrystallized from ethanol.
