(EN) The present invention is concerned with novel compounds having formula (I), the pharmaceutically acceptable acid addition salts thereof and the stereochemically isomeric forms thereof, wherein Alk represents C1-4alkanediyl; D is a bicyclic heterocycle of formula (a) or (b) wherein each R1 independently is C2-6alkenyl; C2-6alkynyl; C3-6cycloalkyl optionally substituted with C1-4alkyl; C1-19alkyl optionally substituted with C3-6cycloalkyl, halo, C1-6alkyloxy or cyano; and each R2 independently is hydrogen or C1-4alkyl. Novel compounds; compositions; processes for preparing novel compounds and intermediates are described.(FR) La présente invention se rapporte à de nouveaux composés de la formule (I), aux sels d'addition acide pharmacologiquement acceptables ainsi qu'aux formes isomères de façon stéréochimique. Dans cette formule, Alk représente alcanediyle; D est un hétérocycle bicyclique de formule (a) ou (b) dans laquelle chaque R1 est indépendamment alcényle C2-6, alcynyle C2-6, cycloalkyle C3-6 facultativement substitué par alkyle C1-4, alkyle C1-19 facultativement substitué par cycloalkyle C3-6, halo, alkyloxy C1-6 ou cyano; et chaque R2 est indépendamment hydrogène ou alkyle C1-4. L'invention concerne donc ces nouveaux composés, des compositions à base de ceux-ci, des procédés de préparation desdits composés ainsi que des intermédiaires de ceux-ci.
The present invention is concerned with novel compounds having the formula ##STR1## the pharmaceutically acceptable acid addition salts thereof and the stereochemically isomeric forms thereof, wherein Alk represents C.sub.1-4 alkanediyl; D is a bicyclic heterocycle of formula ##STR2## wherein each R.sup.1 independently is C.sub.2-6 alkenyl; C.sub.2-6 alkynyl; C.sub.3-6 cycloalkyl optionally substituted with C.sub.1-4 alkyl; C.sub.1-19 alkyl optionally substituted with C.sub.3-6 cycloalkyl, halo, C.sub.1-6 alkyloxy or cyano; and each R.sup.2 independently is hydrogen or C.sub.1-4 alkyl. Novel compounds; compositions; processes for preparing novel compounds and intermediates are described.
