4-Methoxy-N-(4-methoxyphenyl)-N-phenylbenzenamine Usage And Synthesis

Synthesis

To a 1L three-neck flask were added 18.63 g (0.2 mol) of aniline, 78.55 g (0.42 mol) of 4-bromoanisole, 56.10 g (0.5 mol) of potassium tert-butanol and 465.7 g of toluene. Subsequently, 3.66 g (4.0 x 10^-3 mol) of Pd2(dba)3 and 2.32 g (8.0 x 10^-3 mol) of (t-Bu)3PH-BF4 were added as catalysts. The reaction mixture was heated to 100~108°C for 4 hours. After completion of the reaction, the reaction solution was filtered and the filtrate was washed with 200 g of water and dried with anhydrous sodium sulfate. Purification by silica gel column chromatography using toluene as eluent gave a brown viscous liquid. The above crude product was recrystallized with toluene and ethanol (mass ratio 1:2) to afford 51.0 g of 4,4'-dimethoxytriphenylamine in yellow powder form in 83.5% yield.
