4-Chlorobenzoyl chloride → HCID 20298377, compound

Participants

Reaction Steps

Analogously to Example 47b), 10.0 g of ethyl 4-(biphenyl-4-yl)aminobutyrate and 4.6 g of ethyldiisopropylamine in 70 ml of benzene are reacted with 6.2 g of p-chlorobenzoyl chloride to obtain 9.4 g (62.9% of theory) of ethyl 4-[p-chloro-N-(biphenyl-4-yl)benzamido]butyrate as a viscous non-distillable oil. Saponification of this ester, analogously to Example 47c), yields 7.0 g (79.7% of theory) of 4-[p-chloro-N-(biphenyl-4-yl)-benzamido]butyric acid, MP 192° to 194°.
