Triphenylphosphine → HCID 59409859, compound

Participants

Reaction Steps

A mixture of 5-(azidomethyl)-3-(5-chloropyridin-2-yl)-5-methyl-1,3-oxazolidin-2-one (570 mg, INTERMEDIATE 18) and triphenylphosphine (1.12 g) was heated to 65° C. for 4 h in 80 ml of tetrahydrofuran and 10 ml of water. The sample was then cooled to room temperature, and concentrated in vacuo. The residue was purified via column chromatography on a Biotage Horizon 40M column eluting with 100% ethyl acetate (4 column volumes) to remove excess triphenylphosphine and triphenylphosphine oxide, followed by 100% methanol (4 column volumes), to provide the title compound (457 g, 89%). Mass spectrum (ESI) 242.1 (M+1).
