실험 절차

0.29 mole(40.0 g) of 4-hydroxybenzoic acid and 0.35 mole(30.9 g) of (S)-(-)-2-methylbutanol were refluxed for 20 hours in 150 ml of toluene in the presence of 1 ml of conc. sulfuric acid. The reaction solution was concentrated, and then purified by column chromatography to obtain 53.2 g of 4-hydroxybenzoic acid 2-methylbutyl ester [[α]D23 =+4.95°(CHCl3)]. (yield: 88%)
