Pentamethylcyclopentadienyl iridium (III) chloride dimer (CAS#12354-84-6) (10.4 mg) and (1R,2R)-(−)-N-(4-toluene sulfonyl)-1,2-diphenyl ethylene diamine (CAS#144222-34-4) (9.2 mg) were combined in water (120 mL), then heated to 50° C. for 5 h to provide the “Iridium complex.” 1-[4-Bromo-2-(3-methyl-1H-pyrazol-1-yl)phenyl]-2,2,2-trifluoroethanone (16 g, 48 mmol) was dissolved in acetonitrile (120 mL) to which the Iridium complex and potassium formate (3.1 g, 3.7 mmol) were added. The reaction mixture was heated to 50° C. for 8 h. The reaction mixture was then cooled to RT, partitioned between water and EtOAc, and extracted. The combined organic layers were washed with brine, dried over Na2SO4, filtered, and concentrated in vacuo. Recrystallization from hot heptane (200 mL) provided the title compound.
