The synthesis was carried out in the same manner as described in Example 1, except that 30.0 g (0.192 mol) of 3-tert-butylcyclohexanol (cis:trans=2:8) and 13.8 g (0.192 mol) of 1,2-butyleneoxide were used instead of 30.0 g (0.192 mol) of 2-tert-butylcyclohexanol (cis:trans=8:2) and 11.1 g (0.192 mol) of propyleneoxide. 11.3 g of 3-tert-butylcyclohexanol and 9.3 g of 1-(3-tert-butylcyclohexyloxy)-2-butanol (cis:trans=2:8) (bp. 145° to 148° C./10 mm Hg) were obtained in a 32% yield. Then, the cis-trans isomers of 1-(3-tert-butylcyclohexyloxy)-2-butanol were separated from each other in the same manner as described in Example 1.
