実験手順

145 mg (0.5 mmol) of 2-isoquinolin-3-yl-1H-benzoimidazole-4-carboxylic acid (synthesized in Example 1, Step 3)) was reacted with 280 mg (0.75 mmol) of HBTU and 2-amino-3-(3,5-difluoro-phenyl)-propionic acid methyl ester HCl salt (126 mg, 0.5 mmol) as described in general procedure A. After cooling to room temperature, the reaction mixture was diluted with ethyl acetate (30 mL). The organic phase was washed with 1% NaOH aq. solution, then dried over Na2SO4 and concentrated under vacuum. The residue was purified by flash column chromatography (DCM/EtOAc=1:1 then DCM/EtOAc/MeOH=15:15:1) to give 3-(3,5-difluoro-phenyl)-2-[(2-isoquinolin-3-yl-1H-benzoimidazole-4-carbonyl)-amino]-propionic acid methyl ester (120 mg, 50%). LCMS: 487 (M+1)+.
