3- [p-(trans-4-Aminomethylcyclohexylcarbonyl)phenyl] propionic acid hydrochloride (1a), a new anti-ulcer agent, was newly synthesized from trans- or mixed trans/cis-4-aminomethyl-cyclohexanecarboxylic acid and methyl 3-phenylpropionate (4) in three steps. Friedel-Crafts reaction of the acid chloride 3 and 4 was performed without any particular protection of the amino group of 3. 3- [p-(4-Aminomethylbenzoyl)phenyl] propionic acid hydrochloride (1b) was also obtained from 4-aminomethylbenzoic acid in a similar process.
3- [对-(反式-4-氨甲基环己基羰基)苯基]丙酸盐酸盐(1a)是由反式或反式/顺式混合-4-氨甲基环己烷羧酸和 3-苯基丙酸甲酯(4)分三步新合成的一种新型抗溃疡剂。3- [对(4-氨基甲基苯甲酰基)苯基]丙酸盐酸盐(1b)也是用类似的方法从 4-氨基甲基苯甲酸中得到的。
