bis(4-methylphenyl)diazene Use and Manufacturing

General procedure: LiAlH4 (5mmol) was added to a stirred suspension of TiCl4 (1mmol) in diethyl ether. The resulting suspension was stirred at room temperature for 15min. Then a solution in diethyl ether of the corresponding nitro compound (1a, 1mmol) was added slowly to the obtained black reducing suspension under inert nitrogen atmosphere. The reaction was kept stirring at room temperature and monitored by TLC (diethyl ether/petroleum ether 60:40 v/v). After complete conversion of the starting material, the reaction mixture was paper filtered, washed with 1N aqueous NaOH (3×5mL) and once with brine (5mL). The ethereal layers were dried (Na2SO4) and evaporated to dryness under reduced pressure conditions to give the corresponding amine
