Procedure

9.7 g of 2-methyl-3-(2-methyl-5-isopropenyl-cyclopent-1-en-1-yl)-propanol were catalytically hydrogenated in the presence of traces of Raney nickel in methanol. 1130 ml of hydrogen were absorbed and the reaction mixture was filtered, whereupon the clear filtrate was evaporated to give 9.2 g of 2-methyl-3-(2-methyl-5-isopropyl-cyclopent-1-en-1-yl)-propanol; nD = 1.4789; d20 = 0.9084;
