Reaction Steps
A mixture of 4-aminobenzenesulfonamide (190mg, 1.10 mmol), 2-chloro-4-methoxypyridine (135 mg, 0.94 mmol), diacetoxypalladium (13mg, 0.06 mmol), cesium carbonate (417mg, 1.28 mmol) and (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (50 mg, 0.09 mmol) in NMP (2.0 mL) was heated **in the microwave** for 10 min at 150 °C. LC MS crude mix. FLA-04227-80-01 showed no reaction. Another 30 min at 150°C in the microwave provided FLA-04227-80-02 (crude mix.). No product. **Discard.**
