Benzaldehyde, 4-(diphenylamino)- → (4-(Diphenylamino)phenyl)methanol

Participants

Reaction Steps

The compound (1) obtained in Example 1-1, that is, 4-(diphenylamino)benzaldehyde, (4.2 g) was dissolved in 50 mL of ethanol and a solution prepared by dissolving 0.29 g of NaBH4 in 0.1 M aqueous solution of NaOH (15 mL) was slowly added thereto. The reactant solution was reacted at room temperature for 4 hours. An organic layer was separated from the reactant solution using methylene chloride and recrystallized in a methylene chloride/hexane solvent, yielding 92% of a white solid. Data of NMR spectra confirmed that the product had the same structure as the compound (2) in the reaction scheme 2.
