Reaktionsschritte

LiOH (12 mg, 0.50 mmol) in water (0.3 mL) was added to II (33 mg, 0.11 mmol) in THF (0.8 mL) at rt. After 2 h, the reaction mixture was neutralized with 2N HCl, and was then poured onto brine (5 mL), and EtOAc (5 mL) was added. The phases were separated and the aqueous phase was extracted with EtOAc (2×2 mL). The organic phases were combined, dried over MgSO4, filtered, and then evaporated under reduced pressure. The resulting residue was purified by silica gel column chromatography using CH2Cl2/MeOH (100:1 to 100:4) as eluant to furnish III as a colourless oil (18.1 mg, 58%).
