Procedure

2-(2-Hydroxypyridin-3-yl)-5-nitrobenzoic acid (Reference Compound No. 1-3-(3), 50 mg, 0.20 mmol) was dissolved in N,N-dimethylformamide (5 mL), then N,N-diisopropylethylamine (141 μL, 0.81 mmol) and O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (154 mg, 0.41 mmol) were added thereto, and then the reaction mixture was stirred at room temperature overnight. Ethyl acetate (30 mL) was added to the reaction mixture, the whole was washed with water (30 mL) and saturated brine (30 mL) successively. The organic layer was dried over anhydrous magnesium sulfate, and then the solvent was removed under reduced pressure. Chloroform was added to the obtained residue, and then filtered to give the titled reference compound (35 mg) as a pale yellow solid. (Yield 71%)
