Participants

Reaction Steps

A benzene solution (50 ml) of 5-phenyl-3-butyl allophanoyl chloride (0.1 mole) was prepared by reaction of phosgene with 1-phenyl-3-butyl urea by the method of Example 2. This solution was added dropwise to 16.0 g of potassium cyanate in 300 ml of anhydrous DMF as described in Example 3. After similar work-up, 17.0 g (70% yield) of 3-phenyl-5-butyl isocyanuric acid was obtained; b.p. 172° C./.01 mm, m.p. 54°-56° C. IR and NMR analysis were consistent with the assigned structure.
