Ethyl 2-(4-carboxybenzylidene)-7-methyl-3-oxo-5-phenyl-2,3-dihydro-5H-thiazolo[3,2-a]pyrimidine-6-carboxylate–N,N-dimethylformamide (1/1)

Abstract

In the title compound, C24H20N2O5S·C3H7NO, a benzene ring is positioned axially to the pyrimidine ring, which adopts a twist-boat conformation, and is inclined to its mean plane by 85.36 (7)°. In the crystal, inter­molecular C—H⋯O inter­actions result in centrosymmetric head-to-head dimers with an R 2 2(14) graph-set motif along the b axis. Pairs of C—H⋯O and O—H⋯O hydrogen bonds form centrosymmetric head-to-head dimers about inversion centres, corresponding to an R 2 2(7) graph-set motif along the a axis.
