الإجراء التجريبي

A solution of 4,4'-bis(N,N-diethylamino)benzhydrol (11.0 g, 0.034 mole), glycolanilide (5.1 g, 0.034 mole), 37.5 ml of methyl ethyl ketone, 112.5 ml of n-hexane, and 7 drops of methanesulfonic acid was refluxed for about 2 hours, removing water as formed. The solution was then treated with 5 drops of tetramethyl-guanidine and filtered hot. On cooling, the filtrate yielded a tan precipitate. The precipitate was filtered, washed with n-hexane, and dried. The pale yellow solid was recrystallized from 80 ml of methylcyclohexane and 450 ml of acetone to give a solid product, mp 123°-125° C.
