Participants

Reaction Steps

3.1 g (6.7 mmol) of ethyl 2-{3′-[(tert-butoxycarbonylmethylamino)-methyl]biphenyl-4-yloxy}benzoate are placed in 50 ml of dichloromethane and 2.6 ml of trifluoroacetic acid. After stirring at room temperature for 8 hours, the reaction medium is concentrated, placed in water, brought to pH 8 with aqueous 1N sodium hydroxide solution and extracted with ethyl acetate. The organic phase is dried over sodium sulfate, filtered and concentrated under vacuum. 2.3 g of ethyl 2-(3′-methylaminomethylbiphenyl-4-yloxy)benzoate are obtained in the form of an orange-colored oil, in a yield of 95%.
