To a 250 mL round bottom flask was mixed 2-chloroacetaldehyde (5.36 g, 34.2 mmol), NaHCO3 (2.87 g, 34.2 mmol), N-(2,6-diisopropylphenyl)-5-methoxy-[1,1′-biphenyl]-3-carboximidamide (6.6 g, 17.08 mmol) were charged in a flask and 100 mL of iso-propyl amine was added. The reaction mixture was heated up to reflux for 3 hours. The reaction mixture was diluted with water and ethyl acetate. The layers were separated and the aqueous layer was extracted with ethyl acetate. After silica gel chromatography with 10% ethyl acetate in hexane as solvent, 6.9 g of product was obtained.
