A mixture of 3-iodo-1-(tetrahydro-2H-pyran-2-yl)-1H-indazole-4-carbonitrile (50 mg, 0.142 mmol), CuI (13.5 g 0.071 mmol), CsCO3 (2.7 mg, 0.0142 mmol), and 3,4,7,8-tetramethyl-1,10-phenanthroline (0.0142 mg, 3.5 mmol) in EtOH (0.5 mL) under nitrogen in a sealed vial was heated to 90° C. in a microwave oven for 100 min. The reaction mixture was quenched with water and extracted with EtOAc. The extract was dried (MgSO4), filtered, and concentrated in vacuo. The residue was purified by SiO2 chromatography eluting with petroleum ether:EtOAc to afford 3-methoxy-1-(tetrahydro-2H-pyran-2-yl)-1H-indazole-4-carbonitrile as white solid (13 mg, 35.7%). MS (ESI): m/z=258 [M+1]+.
