The asymmetric unit of the title compound, C18H18ClN3OS·C2H5OH, comprises a pyrazoline derivative and an ethanol solvent molecule. In the molecule of the pyrazoline derivative, the pyrazole ring adopts an envelope conformation with the C atom bearing the ethoxyphenyl substituent as the flap. The dihedral angle between the benzene rings is 74.22 (7)°. The ethoxy group is coplanar with the attached benzene ring [C—O—C—Cmethyl = 175.50 (11)° and r.m.s. deviation = 0.0459 (1) Å for the nine non-H atoms]. In the crystal, the pyrazoline molecules are linked by N—H
Oethoxy hydrogen bonds into chains along the c axis and are further linked with the solvent ethanol molecules by N—HOethanol and Oethanol—HS hydrogen bonds. C—Hπ interactions are also present.

In the title compound, C13H12O5, the mean plane of the 2H-chromene ring system (r.m.s deviation = 0.026 Å) forms a dihedral angle of 81.71 (6)° with the mean plane of ethyl 2-hydroxyacetate moiety (r.m.s deviation = 0.034 Å). In the crystal, C—HO hydrogen bonds result in the formation of zigzag layers parallel to the bc plane.

In the title compound, C14H17N3O2, the mean plane of the 1,8-naphthyridine ring system (r.m.s deviation = 0.020 Å) forms a dihedral angle of 23.4 (1)° with the acetamide moiety (r.m.s deviation = 0.001 Å). The molecular structure is stabilized by an intramolecular O—HN hydrogen bond, which generates an S(5) ring motif. In the crystal, molecules are linked into inversion dimers by pairs of N—HO hydrogen bonds, generating 18-membered R22(18) ring motifs.
