Dimethyl Sulfoxide → HCID 20292164, compound

Participants

Reaction Steps

Analogously to Example 19, 8.9 g of ethyl 4-benzhydrylaminobutyrate and 4.3 g of ethyl diisopropylamine are dissolved in 80 ml of benzene and reacted with a solution of 6.8 g of 5-chloro-2-methoxybenzoic acid chloride in 20 ml of benzene. As reaction product one obtains 13.8 g (99% of theory) of ethyl N-(5-chloro-2-methoxybenzoyl)-4-benzhydrylaminobutyrate as a viscous non-distillable oil. The saponification of this ester yields 11.1 g (85.6% of theory) of N-(5-chloro-2-methoxybenzoyl)-4-benzhydrylaminobutyric acid (M.P. 176° to 178°).
