1-Arylsulfonyl-4-phenylthiosemicarbazides(I).-The appropriate 1-arylsiilfonylhydrazide 4 mmol) way dissolved in 95% EtOH (20 ml), followed hy addition of phenyl isocyanate (5.4 g, 4 "01). Refliixing for 30 niiri iollowed by cooling of the aolution gave a white, crybtalliue rolid t,hat was recrystallized from MeOH or EtOH. 2-Arylsulfonylhydrazone-3-phenyl-4-thiazolines(I1).-The appropriate I ( 5 mmol) wa- di-..olved in DXIF (25 ml), and 5 mmol of a-bromoacetophenone ( 1 g, or ethyl a-chloroacetoacet,ate (0.82 g ) was added. The +olutioti was heated 30 min on a steam bath, the dark red liqllid XI. rhilled, and 3 S NHaOH was added to bring it, to pH h. ;\ddition of H 2 0 (100 ml) gave t'he product as a greenijh powder which was wa.5hed several times with H20 and recrystallized i v i i i i i EtOH. 1

Schiff's bases formed by the conden~atioiiof iwiiazide [I] with various benzaldehyde, are reported t o possess antituberculous activity. We have prepared additional Schiff's bases (beiizylideiiei.onicotiiioy1 hydrazonei) which were tested for antituberculous activity by the technique of Doub and Younim-.?
