Procedure

1-(3-tert-Butyl-1-p-tolyl-1H-pyrazol-5-yl)-3-((2-(1-(2,2-dimethoxyethyl)-1H-indazol-5-yloxy)-5-fluorophenyl)methyl)urea (0.500 g, 0.8324 mmol) was dissolved in dichloromethane at room temperature and iodotrimethylsilane (0.3554 mL, 2.497 mmol) added dropwise to the stirred solution. The reaction mixture was monitored by HPLC analysis and when no starting material was detected, the mixture was diluted with dichloromethane and washed with 10% aqueous Na2S2O4, saturated aqueous NaHCO3, brine, dried (MgSO4) and concentrated under reduced pressure to afford 536 mg (quant. yield) of the crude product, which was used without further purification. 1H NMR (400 MHz, DMSO-d6) δ 9.76 (s, 1H), 7.97 (s, 1H), 6.78-7.30 (m, 10H), 6.17 (s, 1H), 5.99 (br, 1H), 5.44 (q, 1H, J=6.1 Hz), 4.46 (m, 4H), H 2.35 (s, 3H), 1.34 (s, 9H).
