Synthesis of new 3,4-di-and 1,2,3,4-tetrahydroquinazolin-4-one derivatives and X-ray diffraction study of crystal solvates of 3-methylsulfonylamino-2-(2-methylsulfonylaminophenyl)-1,2,3,4-tetrahydroquinazolin-4-one

The reactions of hydrazide, mesyl hydrazide, succinyl hydrazide, and maleyl hydrazide of anthranilic acid with carbonyl compounds were studied, and new di-and tetrahydroquinazolin-4-one derivatives were prepared. The structure of one reaction product, viz., 3-methylsulfonylamino-2-(2-methylsulfonylaminophenyl)-1,2,3,4-tetrahydroquinazolin-4-one, was established by X-ray diffraction study of two crystal solvates of this compound. The characteristic features of the crystal packings of these solvates are discussed.
