反応手順
Reflux a mixture of 2-hydroxy-propionic acid (480 ml, 85% in water) and sulfuric acid (2 mL) in acetic acid (2500 mL) and toluene (300 mL) for overnight. After removal of solvent under vacuum, purify the residue by distillation to give 2-acetoxy-propionic acid (550 g, 92%) as colorless oil. 1H NMR (CDCl3, 400 MHz): δ 9.27 (brs, 1H), 5.10 (m, 1H), 2.13 (s, 3H), 1.53 (d, J=7.2, 3H).
