3.6 g of 6-hydroxy-1,4-dimethyl-2,3,3a, 4,5,6,7,8-octahydroazulene were hydrogenated in 25 ml of ethanol with 500 mg of palladium-on-carbon (10%). The reaction mixture was filtered, the filtrate evaporated and distilled under reduced pressure in a bulb-tube. There were obtained 2.5 g of 6-hydroxy-1,4-dimethyl-perhydroazulene; b.p.0.005 ca 82°; IR(film):νmax = 3360, 1460, 1375, 1030, 975 cm-1. The compound has a fresh, woody, earthy odour somewhat reminiscent of vetiver.
