Abstract
Parabanic acid is prepared by a chlorine-free method by reacting 2-methyl-1,3-diazole compounds with nitric acid. Parabanic acid is prepared by nitrating a 2-methyl-1,3-diazole compound of formula (I) with a nitrating acid at 20-50 deg C. (X1, X2 = H, =O, Cl, Br, =N-OH, SH, NH2 or NHR ; and R = alkyl).
