Reaction Steps

The mixture of the 6-Thioureido-pyridine-3-sulfonic acid thiazol-2-ylamide (27 mg, 0.000086 mol) and 1-Bromo-3-(4-chloro-phenyl)-propan-2-one (25 mg, 0.00010 mol) in DMF/AcOH (1:1) was heated at 95° C. for 20 min. The reaction solution was directly purified on Gilson (semi-prep, reverse phase, Phenomenex 100×21.2 mm 10 micron C18 column, 20 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 TFA). Fractions were checked by LC/MS and found no pure desired product was isolated. Fractions with the desired product were combined and then dried on a lyophilizer to give the product (1126-8-P1) as a yellow powder. The product (a mixture) was purified again by chromatography (silica gel, 5% Ethyl acetate in hexanes to 100% Ethyl acetate) to give a cleaner product (1126-8-P2), which was purified by Prep TLC (25% Ethyl acetate in hexanes, then 100% Ethyl acetate) to give the final pure product (1126-8-P-3) as a yellow solid.
