Analogously to Example 59, reacting 7.0 g of ethyl 4-(6-methoxybiphenyl-3-yl)aminobutyrate with 4.6 g of 5-chloro-2-methoxybenzoyl chloride, followed by saponification of the intermediate product, yields 7.1 g (70.1% of theory) of 4-[5-chloro-2-methoxy-N-(6-methoxybiphenyl-3-yl)benzamido]-butyric acid, MP 155° to 156°.
