Abstract

NEW MATERIAL:A 2-benzyl-5-alkyl-hexahydro-benzo(b)-1,6-naphthyridin-10-one derivative of formula I (R is lower alkyl). EXAMLE:2-Benzyl-5-methyl-1,2,3,4-tetrahydro ( 5H, 10H ) -benzo(b)-1,6-naphthyridin-10-one.
USE: Useful as a medicine having analgesic, anti-inflammatory and antihistaminic action.
PROCESS: A-1-benzyl-1'-alkylspiro [ piperidine-4,2'- ( 1',2',3',4'-tetrahydroquinazolin)]-4'-one is reacted with an acylating agent, e.g. an acid anhydride, in the presence of a deacidifying agent, e.g. an organic amine such as pyridine, at 100W 150°C for several hours to give the compound of formula I.
