Reaction Steps

1.4 g sodium hydride (60% in mineral oil) are added to a solution prepared by dissolving 101.5 g of 2-carboethoxy-N-methyl-acetamide in 11 of isopropanol. The reaction is maintained at room temperature for 5 hours. The mixture is neutralised with acetic acid, then the solvent is removed at reduced pressure, and the product is isolated by distillation at 6 mmHg (Teb 115° C.). 91.4 g of 2-carboisopropoxy-N-methyl-acetamide are obtained (yield 82%).
