Procedure

To a solution of 5-bromo-2-methyl-1H-pyrrolo[2,3-b]pyridine (60 mg, 0.284 mmol) in dioxane (3 mL) was added bis(pinacolato)diboron (87 mg, 0.341 mmol), [1,1′-Bis(diphenylphosphino)ferrocene]dichloropalladium(II) complex with dichloromethane (23 mg, 0.028 mmol), potassium acetate (84 mg, 0.852 mmol). The mixture was degassed and heated at 100° C. for 2 h. The mixture was cooled, and then added (S)-ethyl 2-tert-butoxy-2-(7-(4-chlorophenyl)-2-(2-chloropyridin-4-yl)-5-methylbenzo[d]thiazol-6-yl)acetate (100 mg, 0.189 mmol), tetrakis(triphenylphosphine)palladium(0) (22 mg, 0.019 mmol), K2CO3 (131 mg, 0.948 mmol) and water (1 mL, degassed). The reaction mixture was heated at 110° C. for 1 h, cooled and partitioned between ethyl acetate and brine. The organic layer was separated, dried over Na2SO4 and concentrated to give crude which was purified by chromatographic column to afford the desired product. LCMS-ESI+: calc'd for C35H33ClN4O3S: 625.2 (M+H+); Found: 625.3 (M+H+).
