Versuchsvorschrift

A stirring mixture of 68.2 g (0.29 mole) of 3,5-diacetoxybenzoic acid and 21 ml (0.29 mole) of thionyl chloride in 150 ml of dry benzene was heated in an oil bath at 80°-90° C. for 2 hours. After cooling the benzene was removed in vacuo to leave 3,5-diacetoxybenzoyl chloride as a tan, solid which was recrystallized from cyclohexane as colorless crystals, mp 87°-89° C., 61.8 g (83% yield).
