Procedure

Methyl isocyanate (25 ml.) was slowly added to a solution of xanthydrol (30 g.) and triethylamine (1 ml.) in benzene (120 ml.) at 65°C. The solution was kept at 55°C. until evolution of carbon dioxide ceased, refluxed for 11/2 hours, cooled and filtered. The solid was collected and recrystallised from benzene to give N,N'-dimethyl-N-9-xanthenylurea solvated with 2 molecules of benzene, m.p. 170°-171°C.
