실험 절차

10 g (62.8 mmol) of the acrylamido acetal from Example 2 are mixed with 6 g (70.5 mmol) of pyrrolidone and, after addition of one drop of Triton B, the mixture is warmed to 80° C. After 10 minutes, the reaction is terminated. The thin-layer chromatogram shows no UV absorbing acetal. The product is subsequently freed from traces of solvent under a high vacuum. It is a single compound according to TLC. NMR data: 2 methylene protons at each of 2.0, 2.4, 2.5, 3.3, 3.4 and 3.6 ppm(t), 6 methoxy protons at 3.35 ppm(s), 1 acetal proton at 4.4 ppm(t), 1 amide proton at 7.2 ppm.
