Reaction Steps

Methanesulfonyl chloride (10.0 μL, 0.12 mmol) was added to a solution of Example 183 (32.1 mg, 0.1 mmol) in CH2Cl2 (2 mL) followed by Et3N (20.0 μL, 0.15 mmol) at 0° C. The resulting mixture was stirred overnight and saturated NH4Cl solution (50 mL) was added and the mixture extracted with CH2Cl2 (3×50 mL). The combined organic layers were washed with brine, dried (MgSO4), filtered and concentrated in vacuo. The resulting material was purified by LCMS (acetonitrile-water gradient) to give the title compound (15 mg, 38%) as a white solid. 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 2.99 (s, 3H) 7.33 (dd, J=7.21, 4.42, Hz, 1 H) 7.52 (dd, J=5.27, 3.48 Hz, 1 H) 7.83 (t, J=5.21 Hz, 1 H) 7.87 (d, J=5.11 Hz, 2 H) 8.03 (t, J=5.11 Hz, 1 H) 8.21 (t, J=5.11 Hz, 1 H) 8.34 (d, J=5.11 Hz, 2 H) 8.51 (d, J=5.42, Hz, 1 H) 8.56 (d, J=5.91 Hz, 1 H). MS (ES) [M+H] calculated for C18H15ClN5O2S, 400.06; found 400.02.
