Acetic Acid → HCID 136051898, compound

Participants

Reaction Steps

This material was dissolved in ether (50 ml.) and a solution of diazomethane in ether was gradually added thereto under ice-cooling until the color of the mixture was changed to yellow. Acetic acid was immediately added thereto and the mixture was washed with a sodium bicarbonate aqueous solution and a saturated sodium chloride aqueous solution and dried over magnesium sulfate. Ether was distilled off to give oily residue (8 g.). The oily residue was subjected to column chromatography on silica gel using a mixture of benzene and ethyl acetate (9:1) as developing solvent to give methyl 2-methoxyimino-2-(4-hydroxyphenyl)acetate (syn isomer) (6.39 g.).
