Reaction Steps

In an argon atmosphere, the obtained 4-bromo-N,N-dibenzylaniline (425 mg, 1.21 mmol) was dissolved in tetrahydrofuran (5 mL) and cooled to −78° C. A 1.6 M n-butyl lithium hexane solution (1.1 mL, 1.8 mmol) was added thereto, and, 5 minutes thereafter, dimethylformamide (0.186 mL, 2.4 mmol) was further added thereto, followed by stirring for 5 minutes. To the reaction solution was added water, and the mixture was extracted with ethyl acetate. The organic layer was washed with a saturated brine, and then dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (9:1 hexane/ethyl acetate) to obtain 4-(dibenzylamino)benzaldehyde (192 mg, 53%).
