Procedure

To a solution of 5-(5-(3,5-dichloro-4-fluorophenyl)-5-(trifluoromethyl)-4,5-dihydroisoxazol-3-yl)indolizine-8-carboxylic acid (0.9 mmol) and HATU (513 mg, 1.35 mmol) in DMF (18 mL), DIPEA (350 mg, 2.7 mmol) can be added. The reaction mixture can be stirred at rt for 10 min and crude 6-(2-aminoethyl)-3,3-dimethylbenzo[c][1,2]oxaborol-1(3H)-ol hydrochloride (1 mmol) can be added. The reaction mixture can be continued to stir overnight. Water can be added and the mixture can be extracted three times with ethyl acetate. The combined organic layers 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 final title compound.
