Reaction Steps
A mixture of 2,6-di-tertiary-butyl-dimethylamino- p-cresol (131.5 gm, 0.5 mole), boric acid (31.0 gm, 0.5 mole), and benzene (450 ml.) was heated while stirring vigorously at 85° C. for twenty-two hours. Water (5.5 ml.) formed during reaction was collected by azeotropic distillation.At the end of the reaction, the unreacted, insoluble material was removed by filtration, and the benzene was removed under reduced pressure using a rotary evaporator. This gave a golden orange solid (129.5 gm) with a melting point of 75°-80° C.
