Reaction Conditions

Reaction Steps

A mixed solution of ethyl bromide (33.30 g, 0.40 moles)/dried diethyl ether (40 ml) was dropped into a mixture of lithium (4.30 g, 0.62 moles)/dried diethyl ether (25 ml) in 2 hours while stirring at -30° C., followed by further adding dried diethyl ether (40 ml) and raising the temperature to 0° C. The mixture was subjected to separation by filtration. The resulting filtrate was dropped into a mixed solution of 2,2,7,7-tetramethylcycloheptanone (15.00 g, 0.09 moles)/dried diethyl ether (40 ml) in 30 minutes while stirring at 0° C. The mixture was stirred at 0° C. for 2 hours. The resulting reaction mixture was treated in the same manner as in Example 1 to obtain 13.50 g (yield 76.4%) of the captioned compound. This compound was a colorless transparent liquid having a woody, earthy and patchuli oil-like odor.
