Acetic Acid → HCID 66908116, compound

Participants

Reaction Steps

A mixture of 4′-(2-ethoxyethoxy)-2′,6′-dimethyl-3-biphenylcarbaldehyde (0.313 g, 1.05 mmol), ethyl 2-(4-amino-2-fluorophenyl)cyclopropanecarboxylate (0.234 g, 1.05 mmol), acetic acid (0.126 g, 2.10 mmol) and 1,2-dichloroethane (5 mL) was stirred under a nitrogen atmosphere at room temperature for 3 hr. Sodium triacetoxyborohydride (0.445 g, 2.10 mmol) was added to the reaction mixture by small portions, and the mixture was stirred for 3.5 hr. The reaction mixture was concentrated under reduced pressure. Water was added to the residue, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate:hexane=5:95-30:70) to give the title compound (0.456 g, yield 86%) as a yellow oil.
