実験手順

To a solution of 6-aminonicotinic acid (340 mg, 2.4 mmol) and C-(5-benzyl-thiophen-2-yl)-methylamine described in Preparation Example 42 (450 mg, 2.2 mmol) in N,N-dimethylformamide (5 mL) were added benzotriazol-1-yl-tris(dimethylamino)phosphonium hexafluorophosphate (1.1 g, 2.4 mmol) and triethylamine(0.62 mL, 4.4 mmol), and the solution was stirred at 60° C. for 1 hour. Water and ethyl acetate were added to the reaction solution, which was then partitioned, and the organic layer was washed twice with water. Silica gel was added to the organic layer, the solvent was evaporated in vacuo adsorption, purification was carried out by NH silica gel column chromatography (hexane:ethyl acetate=1:1, then ethyl acetate, then ethyl acetate:methanol=10:1), and 6-amino-N-(5-benzyl-thiophen-2-ylmethyl)-nicotinamide (210 mg, 0.65 mmol, 29.5%) was obtained.
