Reaction Steps

1-Cyano-4-hydroxy-7-phenoxy-isoquinoline-3-carboxylic acid methyl ester (75 mg, 0.234 mmol) and 3-(R)-amino-pentanoic acid (82 mg, 0.7 mmol) were placed in a CEM 10 mL Microwave vessel and sodium methoxide-methanol solution (0.5M; 1.4 mL, 0.7 mmol) was added via syringe. The vessel was sealed and heated to 130° C. in a CEM microwave apparatus for 150 minutes. The reaction mixture was diluted with water and treated with 1N hydrochloric acid. The crude precipitate was purified by MPLC (methylene chloride-ethyl acetate) to provide the title compound as an off-white solid in 73% yield. MS ESI(−) m/e: 403.9928 (M−1).
