Reaction Steps

A mixture of 1,1-dimethylindan-5-sulfonyl chloride (0.030 g, 0.13 mmol) and 3-methyl-1-(quinolin-5-yl)-1H-pyrazol-5-amine (prepared from Example 4 step b, 0.028 g, 0.12 mmol) in pyridine (0.12 mL) was heated at 80° C. for 1 h with stirring. After cooling to room temperature, the reaction mixture was concentrated in vacuo. The resulting crude residue was purified by flash chromatography (SiO2, 20% ethyl acetate in hexanes), followed by reverse phase HPLC(C18 column, acetonitrile-H2O with 0.1% TFA as eluent) to give the title compound as a white solid (0.015 g, 0.036 mmol, 28%). 1H NMR (400 MHz, DMSO-d6) δ 10.30 (s, 1H), 8.90 (d, J=3.2 Hz, 1H), 8.06 (d, J=8.4 Hz, 1H), 7.73 (t, J=8.0 Hz, 1H), 7.57 (d, J=9.2 Hz, 1H), 7.46 (dd, J=4.0, 8.4 Hz, 1H), 7.30-7.26 (m, 2H), 7.18 (s, 1H), 7.11 (d, J=8.0 Hz, 1H), 6.05 (s, 1H), 2.71 (d, J=7.6 Hz, 2H), 2.20 (s, 3H), 1.84 (d, J=7.2 Hz, 2H), 1.18 (s, 6H); MS: (ES) m/z calculated for C24H25N4O2S [M+H]+ 433.2. found 433.1.
