To a solution of 5-(5-(3,4,5-trichlorophenyl)-5-(trifluoromethyl)-4,5-dihydroisoxazol-3-yl)indolizine-8-carboxylic acid (0.33 mmol), HATU (188 mg, 0.495 mmol) and Et3N (0.15 mL, 0.99 mmol) in DMF (10 mL) can be added 6-(1-aminoethyl)-3,3-dimethylbenzo[c][1,2]oxaborol-1(3H)-ol hydrochloride (0.93 mmol). The mixture can be stirred at rt overnight and EA (50 mL) can be added. The mixture can be washed with brine, dried over Na2SO4, filtered and concentrated under reduced pressure. The residue can be purified by prep-HPLC to give the title compound.
