Reaction Steps

A solution of methyl 3-{3-[(3-cyanophenyl)carbonyl]-1-(2,2-dimethylpropanoyl)-7-(propan-2-yl)indolizin-2-yl}-2,2-dimethylpropanoate (125 mg, 0.257 mmol), palladium(II) chloride (9.1 mg, 0.051 mmol), and acetamide (152 mg, 2.57 mmol) in THF (1.5 mL) and water (0.5 mL) is heated at 50° C. for 3 h then cooled to 23° C. and partitioned between water and Et2O. The organics are washed with water, dried with MgSO4, filtered, and concentrated in vacuo. Purification of the crude by flash chromatography (SiO2, hexanes to 75% EtOAc in hexanes) gives methyl 3-{3-[(3-carbamoylphenyl)carbonyl]-1-(2,2-dimethylpropanoyl)-7-(propan-2-yl)indolizin-2-yl}-2,2-dimethylpropanoate (114 mg, 88%).
