6-Chloro-pyridine-3-sulfonic thiazol-2-ylamide (200 mg, 0.0007 mol) in 7 M of Ammonia in methanol (5.00 mL) was heated at 160° C. in a pressure bottle for ˜6 h. The reaction had to be stopped because the pressure was too high and some of the reaction solution was leaking. By LC/MS, reaction show ˜30% conversion. The reaction solution was concentrated and then purified on Gilson (Prep LC, reverse phase, Phenomenex 250×30 mm, 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 and dried on a lyophilizer to give the product as a brown oil.
