실험 절차

To a solution of 2-bromobenzoic acid (0.124 g, 0.62 mmol) in DCM (2.25 mL) were added EDCI (0.119 g, 0.62 mmol), HOBt (0.084 g, 0.62 mmol), N-methyl morpholine (0.185 mL, 1.68 mmol) and 2-amino-N-{(1R)-3-methyl-1-[(3aS,4S,6S,7aR)-3a,5,5-trimethylhexahydro-4,6-methano-1,3,2-benzodioxaborol-2-yl]butyl}acetamide (0.2 g, 0.56 mmol). The reaction mixture was allowed to stir for 2 h and was concentrated. The residue was diluted with water and extracted with EtOAc. The organic solutions were combined, washed with brine, dried over MgSO4, filtered and concentrated. The crude product was purified by column chromatography to give 2-bromo-N-[2-({(1R)-3-methyl-1-[(3aS,4S,6S,7aR)-3a,5,5-trimethylhexahydro-4,6-methano-1,3,2-benzodioxaborol-2-yl]butyl}amino)-2-oxoethyl]benzamide (0.22 g, 78%).
