Benzoylene urea

Benzoylene urea is reported to separate from aqueous solution with from one to five molecules of water of crystallization. [Pg.17]

Benzoylene urea has been prepared by passing cyanogen into a solution of anthranilic acid in alcohol and hydrolyzing the resulting 2-ethoxy-4-ketodihydroquinazoline, by fusing anthranilic acid with urea, and by the action of aqueous cyanic acid on anthranilic acid. The procedure described is adapted from that of Bogert and Scatchard with several modifications. [Pg.17]

Dihydroxyquinazoline (benzoylene urea) has been prepared by fusing urea with anthranilic acid or better from 2-ureidobenzoic acid. It can also be prepared from o-ethoxycarbonylaminobenzoni-trile and sodium methoxide followed by hydrolysis (see 5d). [Pg.294]

The statement in Note 5 refers to this salt rather than to benzoylene urea itself. The name F. E. Sheibley is misspelled. [Pg.87]
