実験手順

To a solution of (2S,4R)-1-((3R)-2-((tert-butoxycarbonyl)amino)-3,5-dimethylnon-8-enoyl)-4-hydroxypyrrolidine-2-carboxylic acid (700 mg, 1.6 mmole) in DMSO was added 1-chloro-4-ethoxyisoquinoline (420 mg, 2.0 mmole), prepared above, followed by t-BuOK (1M sol. in THF, 8 mL, 8 mmole) at room temperature under nitrogen atmosphere. The reaction mass was stirred at room temperature for 4 h. The reaction mass was quenched with aqueous citric acid solution and extracted with ethyl acetate. The combined organic layer was dried over anhydrous Na2SO4 and concentrated under reduced pressure to get crude compound. The crude compound was purified by combiflash to get desired product (2S,4R)-1-((3R)-2-((tert-butoxycarbonyl)amino)-3,5-dimethylnon-8-enoyl)-4-((4-ethoxyisoquinolin-1-yl)oxy)pyrrolidine-2-carboxylic acid (600 mg, 64%) as off-white solid. MS: MS m/z 585.1 (M++1).
