Procedure

The solution of 5-(5-(3,4,5-trichlorophenyl)-5-(trifluoromethyl)-4,5-dihydroisoxazol-3-yl)indolizine-8-carboxylic acid (0.665 mmol) and HATU (505.4 mg, 1.33 mmol) in CH3CN (15 mL) at rt can be stirred for 5 min. The mixture can be added to a solution of 5-(aminomethyl)-3,3-dimethyl-benzo[c][1,2]oxaborol-1(3H)-ol hydrochloride (181.1 mg, 0.798 mmol) and TEA (268.7 mg, 2.66 mmol) in CH3CN (15 mL). Then the mixture can be stirred at rt for 2 h. The solution can be acidified with HCl (1 N) and extracted with EA. The combined organic layers can be washed with brine, dried over Na2SO4, and concentrated under reduced pressure. The residue can be purified by prep-TLC to give the final title compound.
