Procedure

Triethylamine (0.025 mL, 0.18 mmol) then triethylsilane (0.96 mL, 6.03 mmol) were added to palladium (II)acetate (12 mg) in DCM (2 mL) and stirred under argon for 15 mins. 3-{[5-(Azetidin-1-ylsulfonyl)-3-bromopyridin-2-yl]oxy}-5-{[(1S)-1-methyl-2-(methyloxy)ethyl]oxy}-N-(1-methyl-1H-pyrazol-3-yl)benzamide (0.175 g, 0.3 mmol) in DCM (2 mL) was added dropwise and the reaction stirred at RT for 24 hours. Methanol was added, the reaction filtered through celite and the solvent removed in vacuo. Ethyl acetate (30 mL) was added and the mixture washed with water (30 mL), citric acid (30 mL), brine (30 mL), dried (MgSO4), filtered and the solvent removed in vacuo to give a white solid. This was chromatographed on silica, eluting with a gradient of 0-100% ethyl acetate in isohexane, to give the desired compound (69 mg).
