To this is added n-butyl lithium, 0.10 mole of a 2.90 molar solution in hexane, followed by the addition of 16.923 g (0.10 mole) of diphenylamine dissolved in ether, 50 ml. The flask contents are stirred magnetically and maintained at -78° C. during the addition of diphenylamine which requires 0.5 hour. The contents are warmed to room temperature for 2 hours.
