Disclosed are novel compounds of formula (I) wherein Ar1, Ra, R4, R5, X and Y are defined below, which are useful as inhibitors of certain protein tyrosina kinases and are thus useful for treating diseases associated with such kinases, for example, diseases resulting from inappropriate cell proliferation, which include autoimmune diseases, chronic inflammatory diseases, allergic diseases, transplant rejection and cancer. Also disclosed are processes for preparing these compounds, novel intermediates useful in these processes and compositions comprising compounds of formula (I).

Cette invention se rapporte à de nouveaux composés représentés par la formule (I), où Ar¿1?, R¿a?, R¿4?, R¿5?, X et Y sont définis dans les pièces descriptives de la demande, ces composés servant d'inhibiteurs de certaines protéine-tyrosine-kinases et étant par conséquent utiles dans le traitement des maladies associées à ces kinase, telles que des maladies résultant d'une prolifération cellulaire inappropriée, notamment les maladies auto-immunes, les maladies inflammatoires chroniques, les maladies allergiques, le rejet des greffes et le cancer. Cette invention concerne également des procédés de préparation de ces composés, de nouveaux intermédiaires utiles dans ces procédés et des compositions comprenant ces composés représentés par la formule (I).
