Abstract
Provided are: a method for producing N,N-dialkylhomofarnesic acid amide, which is a precursor of (±)-3a,6,6,9a-tetramethyldodecahydronaphtho[2.1-b]furan that is useful as a fragrance, at a high recovery rate of a raw material, at a high purity and at a high yield; and a method for producing (±)-3a,6,6,9a-tetramethyldodecahydronaphtho[2.1-b]furan. It is a method for producing N,N-dialkylhomofarnesic acid amide, said method including reacting nerolidol with N,N-dialkylformamide dimethyl acetal under the conditions that the N,N-dialkylformamide dimethyl acetal can be refluxed, wherein the molar ratio of the N,N-dialkylformamide dimethyl acetal to the nerolidol is in a range of 1.5 to 3.
