Procedure

The procedure of Example 1 is repeated using 23.84 grams of 2,6-di-tert-butyl-4-mercaptophenol, 9.8 grams of maleic anhydride, and 0.51 grams of triethylamine. The residue is recrystallized once from hexane-toluene mixture and once from cyclohexane to give 19.0 grams of a light yellow solid, m.p. 92°-93° C.
