Reaction Steps
A mixture of 4-chloro-2-(4-hydroxy-butoxy)-N-methyl-N-pyridin-2-yl-5-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-benzenesulfonamide (150 mg, 0.34 mmol), 5-bromo-2-trifluoromethyl-isonicotinonitrile (111 mg, 0.44 mmol), Pd(Ph3P)4 (40 mg, 0.034 mmol) and Na2CO3 (217 mg, 2.1 mmol) in dioxane (2 mL) and water (0.2 mL) was degassed with N2 for 5 min. The reaction vessel was sealed and then heated at 90° C. for 16 hrs. The mixture was absorbed onto silica gel and purified by chromatography on silica gel eluting with 20-25% acetone in hexanes to give 4-chloro-5-(4-cyano-6-trifluoromethyl-pyridin-3-yl)-2-(4-hydroxy-butoxy)-N-methyl-N-pyridin-2-yl-benzenesulfonamide as an oil (69 mg). A small sample was also purified by prep. LCMS. MS: 541.1 (M+H)+; tR=7.59 min (method 2).
