실험 절차

10 g of the product from Example 4 in solution in ethanol were partially hydrogenated at 50° C under a hydrogen pressure of 100 bars, in the presence of 1 g of Raney nickel, to give the above compound. Yield 85%, boiling point 70°-76° C/0.05 mm Hg, nD25 : 1.4622. Somewhat blander odor than the analogous isopropenyl compound (see Example 4).
