反応手順
0.70 g (2.5 mmol) of 7-benzyloxy-isoquinoline-3-carboxylic acid synthesized above, 1.0 g (2.7 mmol) of HBTU in a mixture of 7.5 ml of DMF and 1.7 mL of DIEA was reacted with 0.48 g (2.5 mmol) of 2-Amino-3H-benzoimidazole-4-carboxylic acid methyl ester (Intermediate A) as described in general procedure A. 2-[(7-Benzyloxy-isoquinoline-3-carbonyl)-amino]-1H-benzoimidazole-4-carboxylic acid methyl ester (1.0 g, 88%) was isolated after column chromatography using 1:1 ethyl acetate and hexane as an eluents. LCMS: 453 (M+1)+.
