Reaction Steps

The mixture of the 2-fluoro-N-thiazol-2-yl-4-thioureido-benzenesulfonamide (32 mg, 0.000048 mol) and 1-bromo-3-(4-chloro-phenyl)-propan-2-one (14 mg, 0.000058 mol) in DMF/AcOH (1:1) was heated at 95° C. for 20 min. The crude product was purified using Gilson preparative HPLC (reverse phase, Phenomenex 250×30 min, 15 micron C18 column, 40 mL/min. Gradient, 85% A to 100% B over 25 min. Solvent A: 7800 water/200 acetonitrile/8 TFA. Solvent B: 7200 acetonitrile/800 water/8). Fractions were checked by LC/MS. The appropriate fractions were combined and dried on a lyophilizer to give the desired product as a light yellow powder (10.8 mg, 47%).
