실험 절차

To a solution of [(2,3-difluorobenzoyl)amino]acetic acid (0.205 g, 0.95 mmol) in dimethylformamide (10 mL) were added TBTU (0.337 g, 1.0 mmol) and (1R)-3-methyl-1-[(3aS,4S,6S,7aR)-3a,5,5-trimethylhexahydro-4,6-methano-1,3,2-benzodioxaborol-2-yl]butan-1-amine as its trifluoroacetate salt (0.362 g, 0.95 mmol). The mixture was allowed to cool to 0° C. and DIEA (0.498 mL, 2.9 mmol) was added dropwise. The reaction mixture was allowed to warm to room temperature and stirred overnight. The reaction was quenched with water (100 mL) and the product partitioned into DCM. The organic layer was dried over sodium sulfate and the solvent removed to give 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.
