Procedure

A flask was charged with 1-cyano-4-hydroxy-7-phenoxy-isoquinoline-3-carboxylic acid (40 mg, 0.13 mmol), HOBt (18 mg, 0.13 mmol) and CH2Cl2 (2 mL). EDC (35 mg, 0.18 mmol) was added, and the mixture was stirred for 10 min. (2S,3R)-3-Amino-2-methyl-butyric acid tert-butyl ester (22 mg, 0.13 mmol) and Hunig's base (0.050 mL, 0.26 mmol) were then added, and the resulting mixture was stirred for 16 h at r.t. Hydrochloric acid (0.1 M) was added to acidify the mixture, and the mixture was extracted with EtOAc. The organic layer was dried over MgSO4 and concentrated. The crude product was purified by column chromatography (0-10% EtOAc/hexanes+2% AcOH) to give 32 mg of the title compound as a white solid. MS: (−) m/z 460.31 (M−1).
