Example 3 Interconversion Between Compounds (VI) A solution of 4-methoxy-3-pyrrolin-2-one (3 g; 26.52 mmols) in absolute ethanol (60 ml) is treated with sodium ethoxyde (2.17 g; 31.82 mmols) under nitrogen atmosphere. The solution is refluxed for 2 hours and then poured into a 30percent NaH2 PO4 solution (200 ml) The resulting mixture is extracted with ethyl acetate (3*150 ml) and the organic phase is shacked with brine, dried over sodium sulphate and evaporated to dryness to obtain 4-ethoxy-3-pyrrolin-2-one (2.19 g; 17.24 mmols). Yield: 65percent. 1 NMR (400 mhz, CDCl3), ppm: 1.38 (3H, t), 3.89 (2H, s), 4.01 (2H, q), 5.03 (1H, s), 6.15 (1H, bs).
