Participants

Procedure

To a solution of the compound (11) (1.0 g; 4.6 mmol). in ethanol (25 ml), sodium acetate (0.754 g; 9.2 mmol) and hydroxylamine hydrochloride (0.384 g; 5.5 mmol) are added, and the resultant mixture is stirred at room temperature for 3 hours. The reaction mixture is poured into ice-water, extracted with chloroform, washed with water and dried. After concentration under reduced pressure, the residue is chromatographed on a silica gel column to give 3-benzyloxymethylcyclohexanone oxime (12) (0.8 g).
