실험 절차
(1S,2S, 4R)-[1-(3,5-Difluorobenzyl)-4-((3aS, 8aR)-2,2-dimethyl-8,8a-dihydro-3aH-indeno[1,2-d]oxazole-3-carbonyl)-2-hydroxyhexyl]-carbamic acid tert-butyl ester (VIII, 60 mg) was dissolved in 5:1 toluene/CH2Cl2 (3 mL), and p-toluenesulfonic acid monohydrate (23 mg) was added. This was stirred at rt for 18 h. The mixture was then filtered, and partitioned between half-saturated NaHCO3 (3 mL) and 1:1 EtOAc/hexanes (2×3 mL). The combined organic layers were dried (MgSO4), filtered, and concentrated under reduced pressure. Flash chromatography of the residue afforded desired product as a solid: MH+370.2.
