Reaction Steps

10 g. of 5% palladium-on-calcium-carbonate catalyst are added to a solution of 94.5 g. of 2,5-dimethyl-α-ethynyl-benzhydrol in 900 ml. of methanol, and the mixture is hydrogenated until the uptake of the calculated amount of hydrogen (about 30 to 40 minutes). The catalyst is filtered off, the filtrate is evaporated, and the obtained crystalline residue is recrystallized from n-heptane. This way 80.7 g. of 2,5-dimethyl-α-ethyl-benzhydrol are obtained, m.p.: 38°-39° C.
