Ethyl 2-amino-4-(4-methyl-1,3-thia­zol-5-yl)-5-oxo-4H,5H-pyrano[3,2-c]chromene-3-carboxyl­ate

There are two independent mol­ecules in the asymmetric unit of the title compound, C₁₉H₁₆N₂O₅S, in which the thia­zole rings make dihedral angles of 80.89 (11) and 84.81 (11)° with the pyrano[3,2-c]chromene ring systems. An intra­molecular N—H...O hydrogen bond involving the amino group occurs in each independent mol­ecule. In the crystal, the amino groups are involved in N—H...O and N—H...N hydrogen bonds.
