A solution of 2-acetoxy-5-(1-benzylpiperidin-4-yl)-1-hydroxyiminopentylamine (0.59 g) in tetrahydrofuran (5 ml) was added dropwise to a solution of 4-nitrobenzoyl chloride (0.29 g) in tetrahydrofuran (5 ml) and the mixture was stirred overnight at ambient temperature and extracted with ethyl acetate. The extract was washed with a sodium hydrogencarbonate aqueous solution and water, dried over magnesium sulfate and evaporated in vacuo to give 2-acetoxy-5-(1-benzylpiperidin-4-yl)-1-(4-nitrobenzoyloxyimino)pentylamine (0.35 g).
