Reaction Steps

4-Chloro-2-fluoro-N-(2-methoxy-phenyl)-N-methyl-5-(4,4,5,5-tetramethyl-[1,3]dioxolan-2-yl)-benzenesulfonamide (57 mg, 0.125 mmol), 5-bromo-4-chloro-2-methyl-pyridine (21 mg, 0.1 mmol), Pd(Ph3P)4 (12 mg, 0.01 mmol), K2CO3 (69 mg, 0.5 mmol) in a mixture of dioxane (1.5 mL) and water (0.15 mL) was degassed with N2 for 5 min. The reaction vessel was sealed and heated at 85° C. for 14 hrs. After the filtration, the mixture was purified by prep. LCMS to afford 4-chloro-5-(4-chloro-6-methyl-pyridin-3-yl)-2-fluoro-N-(2-methoxy-phenyl)-N-methyl-benzenesulfonamide 3-1. MS: 454.7 (M+H)+; tR=7.77 min (method 2). NMR (CDCl3), δ, 8.350 (1H, s), 7.549 (1H, d, J=6.9 Hz), 7.257-7.436 (5H, m), 6.932 (1H, m), 6.817 (1H, m), 3.513 (3H, s), 3.389 (3H, d, J=2.1 Hz), 2.656 (3H, s).
