Procedure

5-Chloro-2-(2,3,4,5-tetrahydro-benzo[b]azepine-1-sulfonyl)-4-(4,4,5,5-tetramethyl-[1,3]dioxolan-2-yl)-phenol (153.0 mg, 0.33 mmol), 5-bromo-4-methyl-pyridine-2-carbonitrile (60 mg, 0.30 mmol), Pd(Ph3P)4 (38 mg, 0.03 mmol) and K2CO3 (138 mg, 1.0 mmol) in a mixture of 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) and dried over MgSO4. After filtration and concentration, the material was purified by TLC plates eluting with ethyl acetate in hexanes (1/3) to give 5-[2-chloro-4-hydroxy-5-(2,3,4,5-tetrahydro-benzo[b]azepine-1-sulfonyl)-phenyl]-4-methyl-pyridine-2-carbonitrile 8-1 as a white solid (100 mg). MS: 453.9 (M+H)+; tR=8.37 min (method 2).
