Reaction Steps

A stirred mixture of 2.0g (7.87 mmol) of α-(6-carbethoxyhexyl)furfuryl alcohol (Example 4), 5.93 ml of 97% formic acid, 268 mg of sodium formate, 10 mg of hydroquinone, and 40 ml of 3:2 dioxane-water is stirred at reflux for 18 hr. The solution is cooled, saturated with salt, and extracted with ether. The extract is washed with brine, dried over magnesium sulfate, and concentrated to give an amber oil.
