Abstract

In the title compound, C(26)H(26)N(2)O(6)S, the benzene ring is positioned axially to the thia-zolopyrimidine ring and bis-ects it with a dihedral angle of 80.94 (7)°. The pyrimidine ring adopts a flattened boat conformation. In the crystal, pairs of bifurcated C-H⋯O hydrogen bonds link the mol-ecules into chains along the c axis.
