Tetrahydrofuran → HCID 178421572, compound

Participants

Reaction Steps

The mixture of trans-4-phenyl-cyclohexanol (86.9 mg, 0.000493 mol), (R)-4-(6-hydroxynaphthalen-2-yl)-4-methyloxazolidin-2-one (Example 4, 100.0 mg, 0.0004111 mol) and triphenylphosphine (129 mg, 0.000493 mol) in tetrahydrofuran (4 mL, 0.05 mol) was heated to reflux, and diisopropyl azodicarboxylate (0.0971 mL, 0.000493 mol) was added dropwise and was stirred and refluxed for 3 hours. TLC monitoring showed the reaction to be complete. The mixture was taken up into DCM and subjected to chromatographic purification with EtOAc/hexane (10:90 to 80:20) to give (R)-4-(6-(trans-4-phenylcyclohexyloxy)naphthalen-2-yl)-4-methyloxazolidin-2-one (160 mg, 97% yield). LCMS 402.28 ([M+1]+, 100%).
