Versuchsvorschrift

A solution of 3-chloro-N-{2-methyl-6-(methyloxy)-3-[3-(methyloxy)phenyl]thieno[2,3-b]pyridin-4-yl}benzenesulfonamide (Example 115) (98 mg, 0.206 mmol) in 37% HCl (2 mL, 24.35 mmol) was heated to 100° C. under nitrogen atmosphere overnight. The reaction mixture was cooled to RT, diluted with MeOH and concentrated in vacuo. The residue was purified by MDAP (acidic conditions), to afford the title compound (58 mg). LCMS (A) m/z: 461 [M+1]+, Rt 1.27 min (acidic).
