A solution (cooled to 10° C.) of 18.1 g. of 4-amino-3,5-dimethoxy-benzaldehyde in 210 ml. of 98% formic acid was treated dropwise with 70 ml. of acetic anhydride with stirring and the temperature was maintained below 15° C. The solution was then stirred for 2 hours at room temperature, treated with 80 ml. of water and evaporated to dryness under vacuum.
