Abstract
PURPOSE: To prepare the titled compound useful as a raw material of pharmaceuticals, etc., easily, in high yield, by using a novel substituted acetaldehyde such as α-phenyl-α-(2-pyridyl)acetaldehyde as a raw material, and reacting with hydroxylamine.
CONSTITUTION: The substituted acetaldoxime of formula II is prepared by reacting a substituted acetaldehyde of formulaI(R1 and R2 are H, lower alkyl, lower alkoxyl, or halogen) (a novel compound) with hydroxylamine (pref. supplied in the form of sulfate, hydrochloride, etc. to the reaction system containing a base such as sodium hydroxide),in a reaction solvent such as benzene. The novel compound of formulaIcan be obtained by the reaction of the corresponding benzylpyridine compound with a formic acid ester in the presence of a strongly basic catalyst.
USE: An intermediate of the corresponding nitrile.
