Reaction Steps
The mixture of spiro[5.5]undecan-3-ol (39.3 mg, 0.000234 mol) and (R)-4-(6-hydroxy-5-(trifluoromethyl)naphthalen-2-yl)-4-methyloxazolidin-2-one (60.6 mg, 0.000195 mol), and triphenylphosphine (61.2 mg, 0.000234 mol) in tetrahydrofuran (2 mL, 0.02 mol) was heated to reflux, and diisopropyl azodicarboxylate (0.0460 mL, 0.000234 mol) was added dropwise and was stirred and refluxed for overnight. The mixture was taken up into methylene chloride and subjected to chromatography purification with EtOAc/hexane (10:90 to 80:20) to give (4R)-4-methyl-4-(6-(spiro[5.5]undecan-3-yloxy)-5-(trifluoromethyl)naphthalen-2-yl)oxazolidin-2-one as a white solid (62.5 mg, 70%). LCMS Rf=2.45 min 462.40 ([M+1]+, 70%), 503.43 [M+42], 100%).
