Reaction Steps

A microwave vial was charged with (S)-ethyl 2-(2-bromo-7-(4-chlorophenyl)-5-methylbenzo[d]thiazol-6-yl)-2-tert-butoxyacetate (50 mg, 0.10 mmol), 2,3-dimethyl-6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-3H-imidazo[4,5-b]pyridine (102 mg, 0.37 mmol), then Pd(PPh3)4 (23 mg, 0.02 mmol). The vial was flushed with argon, diluted with dioxane (2 mL) and to this was added 2M aqueous K2CO3 (0.2 mL, 0.4 mmol). The vial was sealed then heated to 100° C. for 16 hours and then allowed to cool to room temperature. The mixture was diluted with EtOAc, dried over Na2SO4, filtered, and concentrated. The crude residue was purified by silica gel column chromatography (0-100% THF/CH2Cl2 gradient) to afford the desired product. LCMS-ESI+: calc'd for C30H32ClN4O3S: 563.2 (M+H+); Found: 563.2 (M+H+).
