Procedure

A solution of ethyl 3-bromo-1-perhydro-2H-pyran-2-yl-1H-indazole-5-carboxylate (500 mg, 1.41 mmol), 2-benzofuran boronic acid (454 mg, 2.82 mmol), [1,1′-bis(diphenylphosphino)-ferrocene]dichloropalladium (II) complex with dichloromethane (163 mg, 0.141 mmol), and potassium phosphate (1.5 g, 7.05 mmol) in ethylene glycol dimethyl ether (12 mL) was allowed to stir under a nitrogen atmosphere at 90° C. overnight. The reaction was extracted with ethyl acetate and purified by silica gel chromatography to yield the title compound (2.0 g, 90% yield). ES-MS (m/z) 391 [M+1]+.
