Reaction Steps
1-(2-Dimethylaminoethoxy)-10-methyl-9(10H)-acridinone [III; R' is CH3, R" is H, --O--Y--N=Z is 1-O-CH2CH2N(CH3)2 ], hydrochloride salt, m.p. 237°-241° C. (tan granules from methanol-ether). The intermediate 1-chloro-10-methyl-9(10H)-acridinone, m.p. 183°-186° C. (pale yellow granules from ethanol) was prepared by N-methylation of 1-chloro-9(10H)-acridinone, in turn prepared by cyclization of 2-(m-chlorophenylamino)benzoic acid with sulfuric acid.
