By treating 3,4'-dimethyldiphenyl ether under the same conditions as in Example 6 except that 5 ml of ethylene diacetate was added, 2.7 g (14 m. moles) of 2,7-dimethyldibenzofuran and 0.27 g (0.69 m. mole) of the dimer were obtained. The obtained 2,7-dimethyldibenzofuran melted at 82°-83° C. and was in the form of white needle crystals.
