실험 절차

Mesityl chloride (0.28 mL, 3.6 mmol) was added slowly to a cold (−10° C.) solution of benzyl (1R,2R)-1,3-dihydroxy-1-(4-methoxyphenyl)propan-2-ylcarbamate (1.07 g, 3.23 mmol) in pyridine (1.5 mL). The mixture was stirred for 30 min and then pyrrolidine (2.7 mL, 33 mmol) was added slowly to the mixture. The mixture was heated to 45° C. for 6 hours and then the solvent was removed to dryness. After purification by column chromatography (SiO2, using a mixture of CH2Cl2, MeOH, NH4OH), the product was obtained as a clear oil (0.816 g, 66% yield).
