Yield	Reaction Conditions	Operation in experiment
58%		Step 24 ,6 -Difluoro -3 -tributylstannanyl- 1 H-indazo leTo a solution of 4,6-difluoro-3-iodo-lH-indazole (2.11 g, 7.53 mmol) in THF (45 mL) at 0C was slowly added sodium hydride (60%> in mineral oil, 362 mg, 9.04 mmol). The reaction mixture was stirred at room temperature for 10 min then cooled to -10C andisopropylmagnesium chloride (2.0 M in THF, 4.52 mL, 9.04 mmol) was added. The reaction mixture was stirred at -10C for 30 min then tributylchlorostannane (2.66 mL, 9.8 mmol) was added dropwise. Stirring was continued at -10C for 20 min then at room temperature for 3 h. The reaction mixture was quenched with saturated aqueous NH4C1 then diluted with water and extracted with EtOAc (2x). The combined organics were washed with brine then dried over MgS04 and concentrated. The residue was purified by silica gel chromatography with 10%> to 20% EtO Ac/heptane (0.5% Et3N) to afford 1.94 g (58%) of 4,6-difluoro-3-tributylstannanyl-lH- indazole as a pale yellow viscous oil. 1H NMR (CDC13, 300 MHz): ?

The maroon reaction mixture was stirred at room temperature for 2 h then quenched with 10% aqueous Na2S203 and diluted with water. The mixture was extracted with EtOAc (2x). The combined organics were washed with water, sat LiCl, and sat NaCl, then dried over MgSC^ and concentrated to afford 2.18 g of 4,6-difluoro-3-iodo-l H-indazo le as a light brown solid.
