A mixture of 4-[5-Chloro-2-(4,4-dimethyl-3,4-dihydro-2H-quinoline-1-sulfonyl)-4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenoxy]-butan-1-ol (270.0 mg, 0.49 mmol), 5-bromo-2-trifluoromethyl-isonicotinonitrile (112 mg, 0.45 mmol), Pd(Ph3P)4 (57 mg, 0.05 mmol) and Na2CO3 (286 mg, 2.7 mmol) in dioxane (4 mL) and water (0.4 mL) was degassed with N2 for 5 min. The reaction vessel was sealed and then heated at 100° C. for 16 hrs. The mixture was then partitioned between ethyl acetate (20 mL) and water (10 mL). The organic layer was washed with brine (2×10 mL), dried over MgSO4, filtered and concentrated to give a material which was purified by TLC plates eluting with 30% acetone in hexanes to give 5-[2-chloro-5-(4,4-dimethyl-3,4-dihydro-2H-quinoline-1-sulfonyl)-4-(4-hydroxy-butoxy)-phenyl]-2-trifluoromethyl-isonicotinonitrile 11-1 as a white solid (95 mg). MS: 594.2 (M+H)+; tR=2.94 min (method 1).
