Reaction Steps

A mixture of 2-methoxy-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine (13 mg, 0.0878 mmol), (S)-ethyl 2-tert-butoxy-2-(7-(4-chlorophenyl)-2-(2-chloropyridin-4-yl)-5-methylbenzo[d]thiazol-6-yl)acetate (31 mg, 0585 mmol) and 2M potassium carbonate solution (88 μL, 0.178 mmol) in dioxane (0.5 mL) was sparged with nitrogen for 10 minutes. Pd(PPh3)4 (6.9 mg, 0.0059 mmol) was added and reaction mixture was heated in microwave at 100° C. for 1 h . Reaction mixture was diluted with ethyl acetate, washed with brine. The aqueous layer was back extracted with ethyl acetate and the combined organic layer was dried (MgSO4), filtered, concentrated and purified by CombiFlash (0 to 40% EtOAc/Hex) to give product. LCMS-ESI+: calc'd for C33H33ClN3O4S: 602.1 (M+H+); Found: 602.3 (M+H+).
