Reaction Steps
Sodium hydride (50% in oil, 39.6 g) was added portionwise to a solution of ethyl acetoacetate (107.5 g) in dry ether under nitrogen. Valeryl chloride (100 g) was added dropwise over 21/2 hours to the stirred suspension, and then poured into distilled water (500 ml.), and the ether layer was separated off and dried. The ether was removed to give ethyl 2-valerylacetoacetate (142 g) as a yellow oil.
