Summary:1,196,172. 6 - Amino - 2 - aryl - chroman - 4- one hydrazones. P. FOURNARI. 4 Oct., 1967 [5 Oct., 1966], No. 45306/67. Heading C2C. The invention comprises compounds of formula and their pharmaceutically acceptable non- toxic salts, wherein AR is selected from in which X and Y are each H, Cl, Br, I, F, CF 3 , NO 2 , alkyl, alkoxy, alkylthio or dialkylamino, and a process for making them by reacting the corresponding chromanone with hydrazine in an inert solvent. Therapeutic compositions for oral or parenteral administration comprise the above hydrazones, which possess sedative, muscle-relaxant and hypotensive activity, with a diluent or carrier.
