Using the thus-obtained, regenerated Pd/carbon (10 g), the same reaction as in Example II-1 was carried out in a nitrogen atmosphere under normal pressure at 25° C., in which, however, 2,4-di-tert-butylphenyl methanesulfonate (100 g, 0.35 mols), lithium formate (37 g, 0.70 mols) and methanol (600 g) were used. Water (20 mL) was added to the reaction liquid and Pd/carbon was collected through filtration, and heptane (100 g) was added to the filtrate. The organic layer obtained after extraction was concentrated under reduced pressure to give crude 1,3-di-tert-butylbenzene (50 g, yield 75% by mass).
