In a 40 mL vial, 4-Pentyl-cyclohexanol (1144.4 mg, 0.0067202 mol) was diluted with tetrahydrofuran (30.0 mL, 0.370 mol, Acros) and subsequently (R)-4-(6-hydroxynaphthalen-2-yl)-4-methyloxazolidin-2-one (1.4924 g, 0.0061350 mol) and triphenylphosphine (2105.5 mg, 0.0080275 mol) were added and the mixture was stirred. Diethyl Azodicarboxylate in toluene (2.6 mL, 0.0086326 mol, Aldrich) was added, and the mixture was then stirred at room temperature for 38 h. The reaction mixture was evaporated to dryness and chromatographed 0-100% EtOAc/Hexanes (adsorbed onto silica gel). Isolated was 0.6142 g (18%) in approx 70% purity, the remainder being reduced DEAD reagent.
