実験手順

To a solution of 2.5 g (22.9 mmol) of 3-pyridylcarbinol in 100 mL of anhydrous acetonitrile was added 8.8 g (34.4 mmol) of N,N′-disuccinimidyl carbonate and 5.55 mL (68.7 mmol) of pyridine. The solution was stirred for 1 hour and then concentrated in vacuo. The residue was dissolved in ethyl acetate, then washed with saturated sodium bicarbonate, brine, dried over magnesium sulfate, filtered and concentrated to afford 5.3 g of N-Hydroxysuccinimide-3-pyridylmethyl carbonate, mass spectrum m/e=251 (M+H), which was used directly in the next step without purification.
