Participants

Reaction Steps

To a solution of 2.97 g of 4'-amino-3,5-di-t-butyl-4-hydroxybiphenyl in 200 ml of diethyl ether was added a solution of 1.54 g (0.01 mole) of cis-1,2-cyclohexanedicarboxylic anhydride in 75 ml of diethyl ether, and the resulting solution was stirred for about 16 hours. A solid was removed by filtration, rinsed with diethyl ether and hexane and then recrystallized from a mixture of ethyl acetate and hexane to give 3.17 g of solid cis-2-{N-[4-(3,5-di-t-butyl-4-hydroxyphenyl)phenyl]carbamyl}-cyclohexanecarboxylic acid, m.p. 217°-220° C. Analysis: Calculated for C28H37NO4 : % C, 74.5; % H, 8.3; % N, 3.1; Found: % C, 74.6; % H, 8.3; % N, 3.0.
