Procedure
Dissolved 6-(2-Prop-2-ynylcarbamoyl-phenylamino)-1-(tetrahydro-pyran-2-yl)-1H-indazole-3-carboxylic acid methylamide (30 mg) in 1.5 mL of a 90:10:1 mixture of CH2Cl2:Trifluoroacetate TFA:triethyl silane and heat to reflux for 2 hours. Diluted the solution with toluene (40 mL) and concentrate by rotary evaporation to an oil. Dissolved the oil in DMF (1 mL), and filter using a 0.2-micron syringe filter. Used prep-HPLC to isolate the desired compound (12 mg, 50%). 1H NMR (CDCl3-d) δ 9.96 (1H, s), 9.49 (1H, s), 8.28 (1H, d, J=8.85 Hz), 7.47 (1H, m), 7.34 (1H, m), 7.22 (1H, m), 7.15 (1H, dd, J1=8.76 Hz, J2=1.79 Hz), 6.99 (1H, m), 6.86 (1H, t, J=6.97 Hz), 6.31 (1H, m), 4.23 (2H, dd, J1=5.18 Hz, J2=2.54 Hz), 3.49 (3H, s), 2.29 (s,1H).
