실험 절차

To a solution of 2,3-difluoro-N-[2-({(1R)-3-methyl-1-[(3aR,4R,6R,7aS)-3a,5,5-trimethylhexahydro-4,6-methano-1,3,2-benzodioxaborol-2-yl]butyl}amino)-2-oxoethyl]benzamide (0.536 g, 1.2 mmol) in methanol/1N HCl (1:1) (1.5 mL) were added heptanol (1 mL) and isobutyl boronate (0.207 g, 2.0 mmol). The reaction mixture was allowed to stir overnight. The heptanol layer was separated and the methanol/HCl layer was concentrated. The crude product was purified by reverse phase HPLC to give [(1R)-1-({[(2,3-difluorobenzoyl)amino]acetyl}amino)-3-methylbutyl]boronic acid.
