関与物質

反応手順

A 2.0 g portion of hydroxylamine hydrochloride was dissolved in 12 ml of water and 8 ml of 5N sodium hydroxide was added. A 1.0 g portion of 3-(difluoromethoxy)benzaldehyde was added followed by enough ethanol to give a solution. After 10 minutes of reflux, the reaction mixture was concentrated in vacuo and the residue taken up in 10 ml of water. The pH was adjusted to 4 with hydrochloric acid, then the mixture was extracted with chloroform. The organic phase was dried over sodium sulfate and concentrated, giving the desired compound as an oil.
