Procedure
A mixture comprising 3.2 g of α-(3-pyridyl)-2,5-dimethoxy-4,6-dimethylbenzyl alcohol obtained by the method described in any of the Production Examples 1, 2 and 3, 5 ml of pyridine and 5 ml of acetic anhydride was heated and stirred at 80° C. for 1 hour. Then the pyridine and acetic anhydride were distilled off and the residue was purified by silica gel column chromatography. Thus 2.9 g of the title compound was obtained.
