Методика

To the solution of n-pentylmagnesium bromide in tetrahydrofuran synthesized in Example 2, 162 mL (2.0 mol) of ethyl formate was added dropwise in a nitrogen atmosphere and the mixture was stirred overnight at room temperature. After careful addition of water, the reaction mixture was neutralized with dilute hydrochloric acid and extracted with ethyl acetate. The organic layer was washed with a saturated aqueous solution of sodium chloride, dried over anhydrous magnesium sulfate and thereafter concentrated to give 340.8 g of 6-undecanol.
