Add 0.5 mL of 40 mM labeling reagent 1 / dry benzene solution and 0.5 mL of 1 mM alcholol (or amine) / dry benzene (containing 2% of pyridine) solution to a vessel. Close the cap of the reaction vessel and incubate the mixture at 80 °C for 1~2 h (50 °C for 1h, in the case of amine). After cooling to room temperature, excess of 1 is removed by liquid-liquid extraction (e.g. washing with 5%NaHCO3 solution) or solid phase extraction. Use the resultant as an HPLC sample solution.
