2,2,6-Trimethyl-4H-1,3-dioxin-4-one → 2-Ethyl-6-methyl-4-oxo-N-phenyl-4H-pyran-3-carboxamide

Participants

Reaction Steps

The title compound was prepared from 3-oxo-N-phenylvaleramide (m.p. 84.0°-85.5° C.) and 2,2,6-trimethyl-4H-1,3-dioxin-4-one, instead of 2-ethyl-2,6-dimethyl-4H-1,3-dioxin-4-one in Example 15, as the raw materials in a similar way to the method described in Example 15. (Yield: 49%) m.p.: 154.5°-156° C.
