Reaction Steps

In 3 ml of pyridine were added 0.3 g of 6-(2-butynyloxy)-4-benzoylpyrimidine and 0.17 g of O-ethylhydroxylamine hydrochloride, followed by stirring at room temperature for 3 hours. The reaction mixture was then poured into 10% hydrochloric acid and extracted three times with ethyl acetate. The organic layers were combined and washed with a saturated aqueous sodium chloride solution, and the combined organic layer was dried over anhydrous magnesium sulfate and then concentrated. The residue was subjected to silica gel column chromatography to give two isomers of (6-(2-butynyloxy)-4-pyrimidyl)phenylketone O-ethyloxime (referred to as isomers A and B).
