Benzamide N-oxide or its acid-addition salts(I; X = halogen, trifluoromethyl, C3-4 alkyl; Y = H, halogen, nitro group), useful for treatment of melancholia, were prepd. by reacting N-(2-aminoethyl)-morpholine with compd.(II) or its reactive derivs. Compd.(I) was also prepd. by following reaction; (a) reaction of morpholine and compd.(III; R1 = H; R2 = halogen), (b) oxidation of compd. IV), (C) conversion of thioamide(V) to corresponding amide.
