Procedure

α-methylcinnamaldehyde was hydrogenated using copper chromite (2% by weight) as catalyst at a temperature of 150° C. and a pressure of 130° C. psig hydrogen. After the uptake of hydrogen ceased, the mixture was filtered and distilled to obtain the 2-methyl-3-phenylpropanol (b.pt 100° C./1 mm).
