Crystal structure of 3,4-dimethyl 2-(tert-butyl-amino)-5-[2-oxo-4-(thio-morpholin-4-yl)-2H-chromen-3-yl]furan-3,4-di-carboxyl-ate ethyl acetate hemisolvate.

ABSTRACT: In the title hemisolvate, C25H28N2O7S·0.5C4H8O2, the thio-morpholine ring adopts a chair conformation, with the exocyclic N-C bond in an equatorial orientation. The dihedral angle between the coumarin ring system (r.m.s. deviation = 0.044 Å) and the furan ring is 64.84 (6)°. An intra-molecular N-H⋯O hydrogen bond closes an S(6) ring. The ethyl acetate solvent mol-ecule is disordered about a crystallographic inversion centre. In the crystal, the components are linked by C-H⋯O and C-H⋯S hydrogen bonds, generating a three-dimensional network.
