Versuchsvorschrift
To a mixture of 4-hydroxy-N-piperidin-3-ylmethyl-benzamide (135 mg, 0.580 mmol) in tetrahydrofuran (5 mL) was added triethylamine (100 μL) and N-benzyloxycarbonyloxysuccinamide (144 mg, 0.580 mmol) and the mixture stirred at rt for 3 h. The reaction was concentrated in vacuo and chromatographed on silica using 50–100% ethyl acetate/hexane to give 3-[(4-hydroxy-benzoylamino)-methyl]-piperidine-1-carboxylic acid benzyl ester as a foam.
