Reaction Steps

To a solution of tert-butyl 3-(4-(2-((5-bromo-2-carbamoyl-4-chlorophenyl)amino)acetyl)piperazin-1-yl)azetidine-1-carboxylate (350 mg, 0.66 mmol) and cyclopropylboronic acid (226 mg, 2.64 mmol) in toluene (10 mL) and water (2 mL), Pd(OAc)2 (15 mg, 0.07 mmol), PCy3 (37 mg, 0.132 mmol) and K3PO4 (487 mg, 2.31 mmol) were added. The mixture was stirred at 80° C. for 16 h. The mixture was allowed to cool to RT and concentrated in vacuo. The residue was purified by flash column chromatography on silica gel (1-5% methanol/dichloroethane) to afford the desired product (150 mg, 46% yield) as a solid.
