Pyridine → Cyclohexanecarbaldehyde oxime

Participants

Reaction Steps

A solution of cyclohexanecarboxaldehyde (11.2 g, 100 mmol), hydroxylamine hydrochloride (7.2 g, 104 mmol) and pyridine (8.5 mL) in ethanol (150 mL) was stirred for 18 hours, then concentrated in vacuo. The residue was taken up in 10% aqueous citric acid and extracted with ethyl acetate (3×150 mL). The organics were combined, dried over MgSO4 and concentrated to afford cyclohexanecarboxaldehyde oxime which was used directly in the next step.
