N,N'-Dimethylurea → HCID 12876411, compound

Participants

Reaction Steps

In 50 ml of anhydrous dioxane, 3.5 g (0.04 mol) of 1,3-dimethyl urea was dissolved, and under stirring 4.8 g (0.04 mol) of phenylisocyanate was added thereinto. The reaction was carried out at a room temperature for 15 hours, then the reaction mixture was treated a procedure same as in Example 1. The residue thus obtained was recrystallized from ethanol-petroleum ether to obtain 5.0 g (yield 60%) of 1,3-dimethyl-5-phenylbiuret having a melting point of 93°-95° C.
