The title compound, C18H15FN2O4, was synthesized by the reaction of methyl (2-hydroxy­phen­yl)acetate and 3-(4-bromo)phenyl-5-chloro­methyl-1,2,4-oxadiazole. Weak intra­molecular C—H⋯N hydrogen bonds are observed in the crystal structure. [ABSTRACT FROM AUTHOR]

The crystal structure of the title compound, C10H10N2O2, is characterized by an O—H⋯N hydrogen bond. [ABSTRACT FROM AUTHOR]

The title compound, C19H18N2O5, was synthesized by the reaction of methyl (2-hydroxy­phen­yl)acetate and 5-chloro­methyl-3-(3-methoxy­phen­yl)-1,2,4-oxadiazole. The plane of the oxadiazole ring forms a small dihedral angle of 15.2 (2)° with the plane of the benzene ring directly bonded to it, whereas the second benzene ring is approximately orthogonal to the oxadiazole plane, the dihedral angle being 79.1 (2)°.
