New compounds of the formula ##STR1## and the pharmaceutically acceptable acid addition salts thereof, wherein Z.sub.1 and Z.sub.2 are each independently selected from the group consisting of CH.sub.2, CHOB and C.dbd.O, wherein B is selected from the group consisting of hydrogen and alkanoyl; Y is oxygen or sulfur; n is an integer from 0-4 but cannot be zero when Z.sub.1 is CHOB; m is an integer from 0-4 but cannot be zero when Z.sub.2 is CHOB; and R.sub.1, R.sub.2 and R.sub.3 are each independently hydrogen, halogen, hydroxy, trifluoromethyl, alkyl or alkoxy; are antihistamines and are therefore useful in the treatment of respiratory diseases including asthma, hay fever, allergies and the common cold.
该公式的新化合物为##STR1##及其药用可接受的酸盐,其中Z.sub.1和Z.sub.2分别独立地选自CH.sub.2、CHOB和C.dbd.O组成的群,其中B选自氢和烷酰基组成的群;Y为氧或硫;n为0-4之间的整数,但当Z.sub.1为CHOB时不能为零;m为0-4之间的整数,但当Z.sub.2为CHOB时不能为零;R.sub.1、R.sub.2和R.sub.3分别独立地为氢、卤素、羟基、三氟甲基、烷基或烷氧基;它们是抗组胺药物,因此在治疗呼吸道疾病包括哮喘、花粉热、过敏和感冒方面具有用处。
