Procedure

N-(3,5-di tert.butyl-4-hydroxyphenyl)maleamic acid was prepared by adding to the benzene solution of 2,6-di tert.butyl-4-aminophenol in 15 minutes at 15° C. to 31° C. a solution of 9.8 grams of maleic anhydride in 50 milliliters of benzene. The mixture was stirred for 2 hours and the solid product was filtered off and dried. The yield was 19.5 grams and the product melted at 206° C. to 207° C. (with decomposition).
