Versuchsvorschrift
The methyl 8-(3-octyloxiran-2-yl)octanoate (2) (4.8 g; 0.015 mol), Amberlyst 15 (0.05 g) and methanol in excess (100 mL) were placed under reflux for 12 hours. The reaction mixture was filtered and the methanol removed using a rotary evaporator. The reaction mixture was dissolved in dichloromethane (100 mL) and washed with water (3×50 mL). The dichloromethane solution was separated and evaporated to obtain the intermediate compound 3.
