Hydroxyamine hydrochloride → HCID 86754634, compound

Participants

Reaction Steps

Methyl 3-(2-formyl-3,4-dihydro-1-naphthyl)benzoate (0.44 g) was added to a mixture of hydroxylamine hydrochloride (0.11 g) and 28 methanolic sodium methoxide (0.31 ml) in methanol (10 ml) and the whole was stirred for 19 hours at ambient temperature. The solvent was removed by concentration. To the residue was added a mixture of ethyl acetate, tetrahydrofuran and water and adjusted to pH 2 with 6N-hydrochloric acid. The separated organic layer was washed with brine, dried over magnesium sulfate. The solvent was evaporated in vacuo and the residue was purified by column chromatography on silica gel eluting a mixture of chloroform and methanol (50:1). The eluted fractions containing the desired product were collected and evaporated in vacuo to give methyl 3-(2-hydroxyiminomethyl-3,4-dihydro-1-naphthyl)benzoate (0.36 g).
