実験手順

Sodium methoxide (22.6 g) and methanol (450 mL) are charged into a 1 liter single neck round bottom flask equipped with a guard tube and stirred for few minutes to form a clear solution. A mixture of 4-octylphenethyl acetate (58 g) and methanol (50 mL) is added and the mass is stirred for 3 hours at room temperature. Methanol is evaporated and the residue is diluted with water (300 mL) and extracted with ethyl acetate (2×300 mL). The extracts are combined, dried with sodium sulphate and concentrated under vacuum to give crude as yellow color liquid. The crude is purified is by a silica gel column using 30% ethyl acetate/hexane as the eluent to yield the title compound. Yield: 56 g.
