Reaction Steps

A mixture of iridium complex (2.3 g, 3.22 mmol), 8-(4-(4-isobutylphenyl)pyridin-2-yl)-2-methylbenzofuro[2,3-b]pyridine (2.53 g, 6.44 mmol), 2-ethoxyethanol (60 mL) and DMF (60 mL) was heated at 130° C. overnight. The solvent mixture was evaporated under vacuum. The residue was run through a short silica plug. The reaction mixture was further purified by silica gel column with DCM/heptane as elute to obtain 1.8 g desired product (62.6% yield).
