Procedure

20 parts freshly distilled ether, 1.19 parts (0.01 mole) phenyl isocyanate and 0.19 part (0.01 mole) of water were combined and reacted as described in Example 1. The isolation techniques described in Example 2 were conducted. 0.70 part (94% yield) diphenylurea was recovered having a melting point of 253° C. An isocyanate and water produce urea in the absence of a boron complexing agent.
