Triphenylphosphine → (R)-3-((6-(cyclopropylmethoxy)pyridin-3-yl)oxy)pyrrolidin-2-one

Participants

Reaction Steps

A mixture of (S)-3-hydroxy-pyrrolidin-2-one (3.00 g), 6-(2-cyclopropyl-methoxy)-pyridin-3-ol (4.90 g), triphenylphosphine (polymer, 8.56 g), DCM (30 mL) and THF (50 mL) was added DIAD (6.60 g) keeping the reaction temperature below 30° C. After 12 hours the mixture was filtered and the filtrate was evaporated. The residue was purified by SGC (eluent: EA/MeOH 9:1) to provide the title compound. MS ESI+: m/z=249 [M+H]+.
