Reaction Steps

To a solution of 3-iodo-4-nitro-1H-indazole (441 mg, 1.53 mmol) in anhydrous DMF (3 mL) were added potassium carbonate (422 mg, 3.05 mmol), and 5-(bromomethyl)-2-methylthiazole (440 mg, 2.30 mmol) at ambient temperature and under a nitrogen atmosphere. The resulting mixture was stirred at ambient temperature overnight (about 18 hours). The reaction mixture was diluted with water (10 mL) and EtOAc (20 mL). The phases were separated and the aqueous phase was extracted with EtOAc (2×25 mL). The combined organic extracts were concentrated, and the residue subjected to flash liquid chromatography on silica with Hexanes:EtOAc (10:1) as the eluent to afford the desired product (611 mg).
