Procedure

0.13 g of oily sodium hydride and 0.74 g of 6-t-butyl-5-hydroxy-2,3-dihydrobenzofuran-2-spiro-1′-cycloheptane synthesized in Example 7 were treated with 0.33 ml of crotyl bromide in dimethylformamide in the same manner as in Example 8-1) to give 0.82 g of a mixture of geometrical isomers of 5-(2-butenyloxy)-6-t-butyl-2,3-dihydrobenzofuran-2-spiro-1′-cycloheptane as a colorless oil (yield 93%).
