Mode opératoire

To a known compound, 3-(1-ethoxy-ethylideneaminooxy)-propanoic acid methyl ester (CAS No. 97164-30-2, 300 mg, 1.585 mmol) were added methanol (3 ml) and isopropylamine (1.4 ml), and the mixture was stirred at 55° C. for 14 hours. Additional isopropylamine (1.0 ml) was added, and the mixture was stirred for 3 hours using a focused microwave synthesis system (Discover™, CEM) at 100 W. The reaction mixture was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography to give N-(2-isopropylcarbamoyl-ethoxy)-acetimidic acid ethyl ester (46 mg, 13% yield).
