Abstract

Hydroxyphenyl analogues 20, 22, and 24 were prepared by EtSNa-DMF ether cleavage of the corresponding methoxyphenyl analogues 2m, 2n, and 23, respectively, with the secondary amines 20 and 22 going through the N-formyl intermediates 19 and 21. The p- ethoxy analogue 26 was obtained by 0-ethylation of 19, followed by base hydrolysis of the amide 25. The greatest analgesic potency in mouse writhing and rat paw-pain assays was ...
