実験手順

Into 100 ml of dry DMF containing 0.86 g of sodium hydride (purity 60%), were added dropwise 3.9 g of R-form oa 1-trifluoromethyl-heptanol, at room temperature with such a speed not causing too rapid generation of hydrogen, to prepare sodium salt (alkoxide) of R-form oa 1-trifluoromethyl-heptanol After addition was over, stirring was continued further an hour at room temperature, followed by adding thereto 4.80 g of p-iodo-benzonitrile and then refluxing for 2 hours. After cooling, the product was introduced into iced water, and extracted with hexane The hexane phase was washed subsequently with water, 1N-HCl aqueous solution and then water, followed by purifying with silica gel column to obtain 5.16 g of oily oa p-(1-trifluoromethyl-heptyloxy)- benzonitrile.
