Reaction Steps

The synthesis was preformed essentially as described in Method H-L from 4-[2-(4-chloro-2,5-dimethoxy-phenylsulfamoyl)-thieno[3,2-c]pyridin-4-yl]-piperazine-1-carboxylic acid tert-butyl ester (0.112 mmol, 1 equiv.) was used as the thienopyridine in Method C. Yield: 14.7 mg. LC/MS: tR=0.610 (System: 30% to 60% ACN in 1.5 min, YMC), Purity: 92%. MS: 469 (M+1) 1H NMR (270 MHz, DMSO-d6) δ ppm 3.17 (s, 1H) 3.27 (s, 4H) 3.38 (s, 3H) 3.58 (d, J=4.22 Hz, 4H) 3.77 (s, 3H) 7.08 (s, 1H) 7.69 (d, J=5.81 Hz, 1H) 7.81 (s, 1H) 8.16 (d, J=5.81 Hz, 1H) 9.07 (s, 1H) 10.17 (s, 1H).
