Versuchsvorschrift
2-(Beta-cyanoethyl)-2-ethylhexanal was prepared from 2-ethylhexanal and acrylonitrile analogous to the procedure described in Example 1 for 2-(beta-cyanoethyl)2-methylpentanal. Yield 81% of the product boiling at 112°-114° C. at 0.5 mm.; nD20 1.4538. This product was converted to γ-ethyl-γ-n-butyl-δ-valerolactone as described in Example 1 for γ-methyl-γ-n-propyl-δ-valerolactone. Yield 78%, product boils at 104°-105° C. at 0.6 mm.; nD20 1.4652 and exhibits a hairy, lactonic, fatty, costus-like odor.
