Participants

Reaction Steps

Diisopropyl azodicarboxylate (2.1 mL, 10.5 mmol) was added to a solution of [trans-4-(tetrahydro-2H-pyran-2-yloxy)cyclohexyl]methanol (2.05 g, 9.57 mmol), 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol (2.3 g, 10.7 mmol), triphenylphosphine (2.76 g, 10.5 mmol), and triethylamine (1.5 mL, 10.5 mmol) in THF (150 mL) at 0° C. The reaction was allowed to warm to rt and stirred overnight. Water (200 mL) was added and the reaction was extracted with EtOAc (600 mL). The organics were washed with 1 M aq NaOH (4×100 mL), brine, then dried (Na2SO4), filtered and concentrated under reduced pressure. The crude residue was purified via flash chromatography using an eluent of 20% EtOAc in hexanes to afford the title compound as a white solid (1.9 g, 48%). MS (APCI) m/z 417.3 (M+1).
