Procedure

To a suspension of 9.56 g. (0.05 mole) 2-(methoxycarbonylamino)-benzimidazole in 300 ml chloroform a solution of 7.19 g (0.054 mole) 3-methylphenyl cyanate in 20 ml chloroform is added in drops while stirring at 20°C. The reaction mixture is stirred for 5 hours at room temperature and then filtered. The clear filtrate is concentrated under vacuum until dry. The colorless crystalline residue is treated with ether.
