Abstract
1379677 1-Isopropyl-4-(4<SP>1</SP>-fluorophenyl)-7- methyl-2(1H)-quinazolinone SANDOZ Ltd 21 June 1972 [24 June 1971 18 Nov 1971] 29063/72 Heading C2C Novel 1 - isopropyl - 4 - (4<SP>1</SP> - fluorophenyl)- 7-methyl-2(1H)-quinazolinone is prepared (a) by reacting an alkyl (C 1-4 ) N-isopropyl-N-[2- (4<SP>1</SP> - fluorobenzoyl) - 5 - methyl - phenyl] carbamate with an ammonium salt of a C 1-4 aliphatic mono- or di-carboxylic acid or (b) by cyclizing 2 - N - isopropylamino - 4 - methyl- 4<SP>1</SP>-fluorobenzophenone with urea. Alkyl (C 1-4 ) N-isopropyl-N-[2-(4<SP>1</SP>-fluorobenzoyl) - 5 - methyl - phenyl]carbamates are prepared by reacting 2-N-isopropylamino-4- methyl-4<SP>1</SP>-fluorobenzophenone with a C 1-4 alkyl chloro- or bromo-formate. Pharmaceutical compositions having antiinflammatory and analgesic activity comprise, as active ingredient, 1-isopropyl-4-(4<SP>1</SP>-fluorophenyl - 7 - methyl - 2(1H) - quinazolinone, in association with a pharmaceutically acceptable diluent or carrier. Reference has been directed by the Comptroller to Specifications 1,248,430 and 1,181,570.
[GB1379677A]
