Procedure
To a solution of {4-[3-(morpholin-4-ylcarbonyl)-5,5-dioxidothiochromeno[4,3-c]pyrazol-1(4H)-yl]phenyl}methanol (123 mg; 0.28 mmol; 1 eq.) and DIEA (330 μl; 1.93 mmol; 2.56 eq.) in DCM (13 mL) is added at 0° C. methanesulfonlyl chloride (75 μl; 0.97 mmol; 1.3 eq.). The solution is stirred for 30 min and allowed to warm up to rt. After this time, a suspension of sodium iodide (32 mg; 0.21 mmol; 0.28 eq.), K2CO3 (336 mg; 2.43 mmol; 3.22 eq.) and 3-methylmorpholine (166 μl; 1.51 mmol; 2 eq.) in DMF (50 mL) is added on the sulfonylchloride mixture. The resulting suspension is stirred at 80° C. for 2h after which time water is added after return to RT. The product is extracted with DCM and the combined organic layer is washed with brine, dried over MgSO4 and purified by MD-Autoprep then triturated in a mixture of DCM and pentane to afford the title compound as an orange powder. 1H NMR (DMSO-d6): δ 8.02-7.98 (m, 1H), 7.69-7.43 (m, 6H), 6.87-6.79 (m, 111), 4.91 (s, 211), 4.18-4.03 (m, 111), 4.03-3.88 (m, 2H), 3.79-3.56 (m, 8H), 3.56-3.41 (m, 1H), 3.33-3.24 (m, 2H), 3.24-3.10 (m, 1H), 2.52-2.66 (m, 1H), 2.50-2.36 (m, 111), 2.29-2.09 (m, 1H), 1.03 (d, J=6.3 Hz, 3H). HPLC (max plot) 98.1%; Rt 2.09 min. HPLC (max plot) 76.8%; Rt 2.15 min. MS (ESI+): 523.4.
