Reaction Steps

6-Bromo-3-methyl-1,1-diethoxy-3,5-hexadiene is prepared under the conditions described earlier for the preparation of 6-bromo-3-methyl-1,1-dimethoxy-3,5-hexadiene. Starting with 5,5-diethoxy-3-methyl-2-pentenal (4.67 g; 25.1 mmol), 6-bromo-3-methyl-1,1-diethoxy-3,5-hexadiene (5.1 g) is obtained in 77.5% yield. The structure of the product obtained is confirmed by the infrared spectrum and the proton nuclear magnetic resonance spectrum.
