Benzaldehyde → Benzaldehyde, 2,6-dichloro-, oxime

関与物質

反応手順

2,6-Dichloro-benzaldehyde (7.0 g, 40 mmol) and hydroxylamine hydrochloride (2.16 g, 44 mmol) are added to 10 mL of water and 30 mL of methanol. Sodium hydroxide (4.0 g, 100 mmol) is dissolved in 8 mL of water slowly. The sodium hydroxide solution is added to the benzaldehyde solution. The reaction is stirred overnight. The reaction mixture is partitioned between ethyl acetate and water. The organic layer is washed with brine and dried over solid sodium sulfate. The organic layer is filtered and the solvent is removed under reduced pressure to yield the title compound.
