Abstract:
(EN) The instant invention provides intermediates and processes for the preparation of compounds of formula (IV), wherein n is 0, 1, or 2; R is hydrogen or C1-C4 alkyl; X1 is hydrogen, cyano, 4-hydroxybenzoyl, 4-halobenzoyl, or 4-(C1-C4 alkoxy)benzoyl; Y is NR4R5, 4-hydroxyphenyl, or 4-(C1-C4 alkoxy)phenyl; and R4 and R5 are independently hydrogen or C1-C4 alkyl.
(FR) L'invention concerne des intermédiaires et des procédés de préparation de composés de formule (IV) où n vaut 0, 1 ou 2; R représente hydrogène ou alkyle C1-C4; X1 représente hydrogène, cyano, 4-hydroxybenzoyle, 4-halobenzoyle, ou 4-(alkoxy C1-C4)benzoyle; Y représente NR4R5, 4-hydroxyphényle, ou 4-(C1-C4 alkoxy)phényle; et R4 et R5 représentent indépendamment hydrogène ou alkyle C1-C4.
