Reaction Steps

A mixture of trans-4-butyl-cyclohexanol (441 mg, 2.82 mmol), ((R)-4-(6-hydroxynaphthalen-2-yl)-4-methyloxazolidin-2-one (572.5 mg, 2.353 mmol) and triphenylphosphine (741 mg, 2.82 mmol) in tetrahydrofuran (20 mL, 0.3 mol) was heated to reflux, and diisopropyl azodicarboxylate (0.556 mL, 2.82 mmol) was added dropwise. The reaction was stirred and refluxed for 3 hours. TLC and LCMS monitoring showed the reaction to be incomplete. The mixture was concentrated and taken up into dichloromethane and subjected to chromatography purification with EtOAc/hexane (10:90 to 80:20) to give product (0.793 g, 88% yield). LCMS 2.35 min (382.93, [M+1], 100%).
