SPECIFIC COMPOUNDS - 135 Compounds (I) are disclosed e.g. 4-((dibenzylamino)methyl)-N,N-di-para-tolylaniline of formula (Ia), (4-dimethylaminomethyl-phenyl)-diphenyl-amine, (4-((benzyl-ethyl-amino)-methyl)-phenyl)-diphenyl-amine, (4-((benzyl-methyl-amino)-methyl)-phenyl)-diphenyl-amine, and N-(4-(di-para-tolylamino)benzyl)-N-ethyl-4-methylaniline.    EXAMPLE - Under a stream of argon, 12.06 g of 4-(di-para-tolyl-amino)-benzaldehyde, 8.68 g of dibenzylamine, 13.39 g of sodium triacetoxyborohydride, and 100 ml of tetrahydrofuran were stirred at a room temperature for 2 hours. After completion of a reaction, 100 ml of 1M aqueous solution of sodium carbonate was poured into the content, which was stirred for 30 minutes and extracted with ethyl acetate. Organic layer was washed with water and concentrated under reduced pressure to distill the solvent, purified and further worked up to give 4-((dibenzylamino)methyl)-N,N-di-para-tolylaniline (yield 83.1%).
