(8RS)-4-Amino-6-(4-chlorophenyl)-8-(2,4-dichlorothiazol-5-yl)-8,9-dihydro-7H-pyrimido[4,5-b][1,4]diazepine N,N-dimethylformamide monosolvate: sheets built from N-H···N and C-H···O hydrogen bonds.

Abstract

In the title compound, C16H11Cl3N6S·C3H7NO, the seven-membered ring adopts a conformation which is close to the twist-boat form. The molecular components are linked into sheets by a combination of two N-H···N hydrogen bonds and two C-H···O hydrogen bonds. Comparisons are made with other aminopyrimidine derivatives.
