Participants

Reaction Steps

To a solution of (2S,4R)-1-((S)-2-(3-tert-butylureido)-3,3-dimethylbutanoyl)-N-((2S,3S)-1-(cyclopropylamino)-2-hydroxy-1-oxohexan-3-yl)-4-(7-methoxy-2-(1H-pyrazol-1-yl)quinolin-4-yloxy)pyrrolidine-2-carboxamide (2.0 g, 2.72 mmol) in methylene chloride (10 mL) was added the Dess-Martin Periodinane reagent (2.29 g, 5.44 mmol), and the reaction mixture was stirred at room temperature for 1 hour. Completion of the reaction was monitored by TLC analysis. Upon completion the reaction mixture was diluted with water (100 mL) and the organic layer was separated. The aqueous layer was washed with methylene chloride (2×30 mL), and the combined organic layers were washed with saturated sodium bisulfite (20 mL) followed by sodium bicarbonate solution (20 mL), and dried over sodium sulfate. The solution was filtered, the filtrate concentrated under reduced pressure, and the resulting residue was stirred with hexane (10 mL). The solid was filtered and dried to provide 1.75 g (87.8%) of (2S,4R)-1-((S)-2-(3-tert-butylureido)-3,3-dimethylbutanoyl)-N-((S)-1-(cyclopropylamino)-1,2-dioxohexan-3-yl)-4-(7-methoxy-2-(1H-pyrazol-1-yl)quinolin-4-yloxy)pyrrolidine-2-carboxamide as white solid (HPLC purity: 97.3% by area; HPLC retention time: 22.58 minutes).
