Procedure

A mixture of 6-chloro-3-iodo-1-(tetrahydro-2H-pyran-2-yl)-1H-indazole-4-carbonitrile (600 mg, 1.550 mmol), K3PO4 (644 mg, 3.037 mmol), PdCl2(dppf) (186 mg, 0.228 mmol), and 2,4,6-trimethyl-1,3,5,2,4,6-trioxatriborinane (290 mg, 1.52 mmol) in dioxane (2 mL) under nitrogen in a sealed vial was heated at 100° C. in a microwave oven for 18 h. The reaction mixture was quenched with EtOAc and water. The organic layer was concentrated in vacuo to afford 6-chloro-3-methyl-1-(tetrahydro-2H-pyran-2-yl)-1H-indazole-4-carbonitrile as white solid (230 mg, 53.9%). MS (ESI): m/z=276 [M+1]+.
