Reaction Conditions

Reaction Steps

To a solution of N-(2-bromo-3,6-dimethylthieno[2,3-b]pyridin-4-yl)-3-chlorobenzenesulfonamide (Example 77) (100 mg, 0.232 mmol) in 1-methylimidazole (1.5 mL, 18.82 mmol) was added potassium ferrocyanide (17.06 mg, 0.046 mmol) and copper(I) iodide (4.41 mg, 0.023 mmol) and the reaction stirred at 160° C. for 16 h. The reaction mixture was then cooled to RT before directly purifying on silica, eluting with a gradient of 0-20% 2M NH3 in MeOH in DCM. Further purification by MDAP (acidic conditions), afforded the title compound (25.1 mg). LCMS (A) m/z: 378 [M+1]+, Rt 1.10 min (acidic).
