Reaction Steps

To a solution of 2-{3-bromo-5-[1-(triphenylmethyl)(1,2,4-triazol-3-yl)]-1H-indazolyl}perhydro-2H-pyran (0.150 g, 0.254 mmol), in ethylene glycol dimethyl ether (3 mL) was added 4-methylphenyl boronic acid (0.052 g, 0.381 mmol), [1,1′-bis(diphenylphosphino)-ferrocene] complex with dichloromethane (1:1) (0.030 g, 0.0254 mmol) and potassium phosphate (0.269 g, 1.27 mmol). The reaction mixture was heated to reflux temperature for 5 hours. The solvent was then evaporated to dryness and the residue was dissolved in 20 mL of ethyl acetate. The heterogeneous solution was washed 3 times with 10 mL of water and once with 10 mL of brine. The organic layer was dried over Na2SO4 and evaporated to dryness. The resulting brown solid was adsorbed on silica gel and purified by column chromatography (85:15 hexanes/ethyl acetate) to provide the title compound (0.130 g, 85% yield): ES-MS (m/z) 602 [M+1]+.
