실험 절차

A mixture of (R)-4-(6-(cis-4-butylcyclohexyloxy)naphthalen-2-yl)-4-methyloxazolidin-2-one (Example 5, 113.2 mg, 0.0002967 mol), N-iodosuccinimide (74.8 mg, 0.000332 mol) and zirconium tetrachloride (10 mg, 0.000044 mol) in methylene chloride (2.43 mL, 0.0380 mol) was heated to reflux under argon in a vial overnight. The precipitate was filtered off and the residue was purified with Isco column eluted with EtOAc in hexane from 0 to 40% to give the product as a solid (128.9 mg, 86% yield). NMR showed identity.
