This compound has been obtained by two related ways: 1) The condensation of 4-acetylbiphenyl oxime (I) with 2-(2-bromoethoxy)tetrahydropyran (II) by means of K2CO3 in hot dimethylacetamide gives the oxime derivative (III), which is treated with TsOH in methanol yielding 4-acetylbiphenyl O-(2-hydroxyethyl)oxime (IV). The condensation of (IV) with 5-(4-hydroxybenzyl)-3-tritylthiazolidine-2,4-dione (V) by means of diethyl azodicarboxylate (DEAD) and PPh3 in THF affords (VI), the trityl derivative of the target compound, which is finally treated with hot aqueous ethanol to eliminate the trityl group. 2) The condensation of 5-(4-hydroxybenzyl)thiazolidine-2,4-dione (VIII) with N-(2-hydroxyethoxy)phthalimide (VII) by means DEAD gives the adduct (IX), which is treated with hydrazine to eliminate the phthalimido group yielding the substituted hydroxylamine (X). Finally, this compound is condensed with 4-acetylbiphenyl (XI) by means of TEA.

This compound has been obtained by two related ways: 1) The condensation of 3-acetyl-6-phenylpyridine oxime (I) with 2-(2-bromoethoxy)tetrahydropyran (II) by means of K2CO3 in hot dimethylacetamide gives the oxime derivative (III), which is treated with TsOH in methanol yielding 3-acetyl-6-phenylpyridine O-(2-hydroxyethyl)oxime (IV).
