To a vial flushed with argon was added (S)-ethyl 2-(2-bromo-7-(4-chlorophenyl)-5-methylbenzo[d]thiazol-6-yl)-2-tert-butoxyacetate (100 mg, 0.202 mmol), 1,3-dimethyl-1H-indazol-6-ylboronic acid (76 mg, 0.4 mmol), Pd(PPh3)4 (23 mg, 20 μmol), and K2CO3 (83 mg, 0.6 mmol). De-gassed dioxane (1.6 mL) and water (0.4 mL) were then added, and the reaction was heated to 100° C. for 1 h. After cooling to 23° C., the reaction was filtered over a plug of Celite, concentrated, and purified by column chromatography (gradient 0 to 30% EtOAc in hexanes) to give the product. LCMS-ESI+: calc'd for C31H33ClN3O3S: 562.2 (M+H+); Found: 562.3 (M+H+).
