실험 절차

Stir a mixture of 2-acetoxy-propionic acid (550 g, 4.16 mol) in oxalyl chloride (500 mL) at room temperature for overnight. After removal of oxalyl chloride under vacuum, ˜700 g crude product is obtained (quantitative yield crude), which is used directly in the next step. 1H NMR (CDCl3, 400 MHz): δ 5.16 (m, 1H), 2.13 (s, 3H), 1.58 (d, J=7.2, 3H).
