摘要:
A process for the preparation of a compound of the formula I or a salt thereof ##STR1## wherein R.sup.1 and R.sup.2 each represent hydrogen or a C.sub.1-4 alkoxy group, or together form a methylenedioxy group;R.sup.3, r.sup.4, r.sup.5 and R.sup.6 are the same or different and are hydrogen or a group of the formula --CH.sub.2 --(CH.sub.2).sub.n --R.sup.7 with the proviso that at least one of the members R.sup.3, R.sup.4, R.sup.5 and R.sup.6 is other than hydrogen; R.sup.7 is carboxyl or a carboxylic acid derivative group;N = 0.1 or 2 which comprises reacting a compound of the formula II ##STR2## with an organic secondary amine and reacting the N-amine of the formula III ##STR3## thus obtained wherein R.sup.8 and R.sup.9 each represent a C.sub.1-5 alkyl group, or together with the adjacent nitrogen atom form a 5- or 6-membered heterocyclic ring which can contain a further heteroatom, with a compound of the formula IVch.sub.2 .dbd. ch -- (ch.sub.2).sub.n -- R.sup.10 (IV)wherein R.sup.10 is a cyano or alkoxycarbonyl group.
摘要:
An antiphlogistic compound of the formula (I) ##STR1## or a pharmaceutically effective salt thereof wherein R.sup.1 and R.sup.2 are hydrogen or C.sub.1-4 alkoxy or together form a methylenedioxy group;R.sup.3, R.sup.4, R.sup.5, and R.sup.6 are hydrogen or a group of the formula --CH.sub.2 --(CH.sub.2).sub.n -R.sup.7 with the proviso that at least one of R.sup.3, R.sup.4, R.sup.5 and R.sup.6 is other than hydrogen;R.sup.7 is a carboxylic group or a carboxylic acid derivative group; n=0, 1 or 2, provided that if R.sup.3, R.sup.4 and R.sup.5 are hydrogen and R.sup.7 in the group R.sup.6 is cyano or alkoxycarbonyl, and n=1, then R.sup.1 and R.sup.2 are hydrogen, C.sub.2-4 alkoxy, or together form a methylenedioxy group.
摘要:
There are provided new compounds of the formula I ##STR1## wherein both R.sup.1 moieties stand for an alkyl group having 1 to 4 carbon atoms or form together a methylene bridge,R.sup.2 is cyano or an alkoxycarbonyl group having 1 to 4 carbon atoms in the alkoxy position,R.sup.3 is hydroxy or alkanoyloxy having 1 to 4 carbon atoms in the alkoxy position in .alpha.-position or .beta.-steric position,and acid addition salts thereof. There is also provided a process for the preparation of the compounds of the formula I.
