Reaction Steps
Analogously to Example 47, 16.0 g of ethyl 4-(biphenyl-2-yl)aminobutyrate and 7.3 g of ethyldiisopropylamine in 70 ml of benzene are reacted with 4.4 g of acetyl chloride to obtain, as reaction product, 14.0 g (76.2% of theory) of ethyl 4-[N-(biphenyl-2-yl)acetamido]butyrate as a viscous non-distillable oil. The saponification of this ester and recrystallization of the crude product obtained from isopropyl alcohol yields 10.1 g (79.0% of theory) of 4-[N-(biphenyl-2-yl)acetamido]butyric acid, MP 124° to 125°.
