The first preparation of acridin-9(10H)-ones carrying a tertiary thiocarbamoyl group at C(10), i.e., N,N-dialkyl-9-oxoacridine-10(9H)- carbothioamides 9, is described. The method is based on the reaction of (2-halophenyl)(2-isothiocyanatophenyl)methanones 7, prepared from (2-aminophenyl)(2-halophenyl)methanones 5 by a convenient three-step sequence, with secondary amines in DMF at room temperature to generate the corresponding thiourea derivatives 8 in situ, which are treated with NaH at 100-120° to provide the desired products in one-pot reactions in generally good yields.
