実験手順

To a solution of (4-aminomethylphenyl)-benzylamine described in Preparation Example 19 (369 mg, 1.74 mmol) and 2-amino-6-chloro-nicotinic acid (300 mg, 1.74 mmol) in N,N-dimethylformamide (10 mL) were added benzotriazol-1-yloxytris(dimethylamino)phosphonium hexafluorophosphate (924 mg, 2.09 mmol) and triethylamine (0.49 mL, 3.48 mmol), and the solution was stirred overnight at room temperature. Ethyl acetate and water were added to the reaction solution, which was then partitioned, the organic layer was washed with water, and then, dried over anhydrous magnesium sulfate. The solvent was evaporated, the residue was purified by silica gel column chromatography (hexane:ethyl acetate), and the title compound (310 mg, 49%) was obtained as a pale yellow solid.
