Procedure

To methyl 2-[2-(biphenyl-4-yloxymethyl)phenyl]-2-oxoacetate (3.46 g, 0.01 mol), added were anhydrous methanol (10 ml), dry THF (10 ml) and a 40% solution (2.33 g) of methyl amine (0.03 mol) in methanol, and the reaction mixture was stirred at room temperature for 2 hour. After completion of the reaction, water (150 ml) was added to the reaction mixture which was then adjusted to below PH 2 by addition of conc. HCl and extracted with ethyl acetate (150 ml). The extract was dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The obtained crystals (3.42 g; yield, 99.1%) were recrystallized from ethyl acetate/n-hexane to give N-methyl-2-[2-(biphenyl-4-yloxymethyl)phenyl]-2-oxoacetamide (2.83 g) as colorless crystals (m.p.: 144°-145° C.).
