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