Participants

Reaction Steps

General Procedure D To a solution of 4-[(3,5,5,8-Tetramethyl-5,6-dihydronaphthalen-2-yl)amino]benzoate (Compound 15, 0.20 g, 0.58 mmol) and 5 mL of THF was added acetaldehyde (0.30 mL, 5.8 mmol), followed by NaBH3CN (0.10 g, 1.74 mmol) and glacial acetic acid (2 mL). The resulting reaction mixture was stirred at room temperature for 24 h, then treated with water and ethyl acetate. The layers were separated, and the aqueous layer was extracted three times with ethyl acetate. The combined organic layers were washed with NaHCO3 1 N, brine, and dried over MgSO4, and filtered. The solvent was removed, and the residue was purified by flash column (hexane:ethyl acetate=4:1) to give 0.19 g (88%) of the title compound as a light yellow solid.
