Participants

Reaction Steps

To a stirred solution of 3-bromo-1-perhydro-2H-pyran-2-yl-1H-indazole-5-carbonitrile (1.47 g, 4.82 mmol) in dimethoxyethane (24.0 mL) was added 3-hydroxyphenylboronic acid (1.60 g, 7.27 mmol), dichloro[1,1′-bis(diphenylphosphino) ferrocene]palladium (0.396 g, 0.485 mmol), and potassium phosphate (5.12 g, 24.1 mmol) and the mixture was heated at reflux for 48 h. The mixture was diluted with dichloromethane. The organic extracts were washed with saturated sodium bicarbonate, dried over anhydrous sodium sulfate, filtered and evaporated. Purification of the residue by column chromatography with 20–50% ethyl acetate/hexanes furnished the product (1.31 g, 85% yield). ES-MS (m/z) 320 [M+1]+
