【 摘 要 】
In the title hemisolvate, C25H28N2O7S·0.5C4H8O2, the thiomorpholine 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 intramolecular N—H⋯O hydrogen bond closes an S(6) ring. The ethyl acetate solvent molecule 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.
