実験手順

To a solution of quinoxaline-6-carboxylic acid described in Preparation Example I-1 (15 mg, 0.063 mmol) and 4-phenoxybenzylamine described in Preparation Example 3 (13 mg, 0.063 mmol) in N,N-dimethylformamide (2 mL) were added benzotriazol-1-yloxytris(pyrrolidino)phosphonium hexafluorophosphate (36 mg, 0.069 mmol) and triethylamine (19 μl, 0.14 mmol), which was then stirred at room temperature for 24 hours. The reaction mixture was concentrated, the residue was purified by reverse phase high performance liquid chromatography (acetonitrile-water mobile phase (containing 0.1% trifluoroacetic acid) was used), and the title compound (12 mg, 0.025 mmol, 40%) was obtained as a trifluoroacetic acid salt.
