To a degassed mixture of tert-butyl 2-fluoro-6-iodobenzoate (161 mg, 0.5 mmol), 4,4,5,5-tetramethyl-1,3,2-dioxaborolane (0.1 mL, 0.6 mmol) and TEA (0.25 mL, 1.5 mmol) in 2 mL dioxane, was added Pd(PPh3)2Cl2 (7 mg, 0.01 mmol). The mixture was stirred at 165° C. for 10 min in a microwave oven. The mixture was diluted with EtOAc, washed with sat. NH4C1, H2O and brine, dried over (Na2SO4), filtered and concentrated. The crude product was purified by flash chromatography (0-10% EtOAc/hexanes gradient) to afford 50 mg (45%) of Intermediate 436.2.
