40 g of Raney nickel (water-wet) are added to 124.84 g of [3-(5-methyl-1,2,4-oxadiazol-3-yl)phenyl]methanol (569.39 mmol) in a mixture of 1300 ml of methanol, 100 ml of glacial acetic acid and 100 ml of water, and the mixture is hydrogenated at room temperature and atmospheric pressure until 14.7 I of hydrogen have been taken up (45 h). For work-up, the catalyst is filtered off, and the solution which remains is evaporated to dryness, and the residue is boiled up in methyl tert-butyl ether and filtered off. The crystals are dried overnight in vacuo.
