실험 절차

A reaction mixture comprising 83 g of ethyl 4-[6-(3-methyloxetan-3-ylmethoxy)hexyloxy]benzoate, 12 g of sodium hydroxide, 50 ml of water and 200 ml of Solmix (registered trade mark) was refluxed for 2 hours. This was made acidic with hydrochloric acid, and extracted with ethyl acetate. The organic layer was dried with anhydrous magnesium sulfate. The solvent was evaporated away, and 63 g of 4-[6-(3-methyloxetan-3-ylmethoxy)hexyloxy]benzoic acid (OX1) was obtained. m.p.: 58.5° C.
