Versuchsvorschrift

O-(7-Azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (630 mg, 1.7 mmol) was added to a solution of 2-(2-tert-butoxycarbonylaminopyridin-4-ylmethylthio)pyridine-3-carboxylic acid (Reference compound No. 9-1, 500 mg, 1.4 mmol), 3,5-xylidine (180 mg, 1.5 mmol) and N,N-diisopropylethylamine (0.72 mL, 4.1 mmol) in N,N-dimethylformamide (7 mL) at room temperature, and the mixture was stirred for 12 hours. Ethyl acetate (30 mL) was added to the reaction mixture, then the whole was washed with brine (50 mL) and dried over anhydrous magnesium sulfate. The organic layer was evaporated under reduced pressure, then the resulting residue was purified by silica gel column chromatography to give 670 mg of the target compound quantitatively as a colorless solid.
