反应详情

A solution of 6-bromopyridine-2-carbaldehyde (334 mg, 1.80 mmol) and 1-(aminooxy)-2-methylpropan-2-ol hydrochloride salt (254.6 mg, 1.80 mmol) were stirred in ethanol (5 ml) for one hour at 10° C. The reaction mixture was cooled to room temperature and diluted with ethyl acetate. The organic layer was washed with water, dried over magnesium sulfate, filtered, and concentrated under reduced pressure. Column chromatography from 100% hexanes to 30% ethyl acetate afforded the title compound as E/Z mixture.
