Cinnamic acid amide

摘要

ANTIPHLOGISTIC AND ANTIPYRETIC CINNAMIC ACID AMIDES G3A- Are new compounds of formula (I): (where R1 is Br or I and R2 is piperidino, 4-hydroxypiperidino or morpholino). Prepared by (a) reacting (II): (where X is OH, NH2, NH(lower alkyl) or N(lower alkyl)2 or a reactive residue, e.g. halogen, alkoxy or acyloxy) with H-R, or a reactive deriv. thereof or (b) olefinating (IV) with (V): (where A is (R3O)2P-CH2- in which R3 is lower alkyl, or (R4)3P=CH- in which R4 is aryl or alkyl), the reaction being carried out in the presence of a base when A is (R3O)2P-CH2-. Use is as antiphlogistics and antipyretics (better than phenylbutazone in kaolin- and carrageenin-oedema tests).
