Triphenylphosphine → 2-((4-Fluorotetrahydro-2h-pyran-4-yl)methoxy)-5-iodo-3-(trifluoromethyl)pyridine

Participants

Reaction Steps

A mixture of EXAMPLE 37C (0.537 g), 5-iodo-3-(trifluoromethyl)pyridin-2-ol (1.156 g), and triphenylphosphine (1.574 g) in tetrahydrofuran (20 mL) was cooled to 0° C. To this solution was added (E)-di-tert-butyl diazene-1,2-dicarboxylate (0.921 g). The reaction mixture was stirred overnight. The solvent was removed, and the residue was purified with column flash chromatography on silica gel eluting with 4:1 hexanes/ethyl acetate to give the desired product.
