실험 절차
In a 10 L round-bottomed flask 8-{[2-(methyloxy)ethyl]oxy}-1,4-dioxaspiro[4.5]decane D60 (151 g, 700 mmol) was dissolved in tetrahydrofuran (THF) (3000 mL) to give a colourless solution. 3M hydrochloric acid (2333 mL, 7000 mmol) was added. Reaction was allowed to stir at room temperature overnight. The organic solvent was partially evaporated under vacuum and then the aqueous layer was back extracted with DCM (3×500 mL). The organic phase was dried over Na2SO4, filtered and concentrated to obtain 121 g of crude material as yellow oil. The crude product was purified by Biotage® 75 L SiO2 column eluting with c-hex/EtOAc 8/2 to get title material (76 g; 63%).
