    摘要: Benzophenone derivatives are produced which have the formula ##STR1## wherein R.sub.1 signifies hydrogen, nitro, halogen or trifluoromethyl; R.sub.2 represents hydrogen or halogen; R.sub.3, R.sub.4 and R.sub.5 are the same or different and signify hydrogen or lower alkyl; R.sub.6 and R.sub.7 each represent lower alkyl or together with the nitrogen atom form a morpholino, 4-(lower alkyl)-1-piperazinyl, 1-pyrrolidinyl or piperidino group, A signifies an alkylene group with 2 to 8 C atoms and Y represents oxygen or a group ##STR2## R.sub.8 and R.sub.9 each signifying lower alkyl or together signifying lower alkylene.The benzophenone derivatives and their pharmaceutically acceptable salts exhibit sedative, anti-convulsant, muscle relaxant and anxiolytic activities.Also provided are methods for the preparation of these compounds.
