Ethyl 2-methyl-6-(propan-2-ylamino)-4-sulfanylidene-3H,11H-pyrimido[1,6-c]quinazoline-1-carboxylate

Ethyl 2-methyl-6-(propan-2-ylamino)-4-sulfanylidene-3H,11H-pyrimido[1,6-c]quinazoline-1-carboxylate

The title compound, C18H22N4O2S, contains a substituted pyrimidine ring fused to both a benzene ring and a substituted thioxopyrimidine ring. The pyrimidine and thioxopyrimidine rings adopt distorted chair conformations. In the crystal, adjacent molecules are linked by pairs of N—H...S...
