Reaction Steps

Under cooling with ice and stirring, 798 mg of the above ethyl (2-imino-4-thiazolin-4-yl)-2-sulfoacetate is added to 6.6 ml of 1N-sodium hydroxide and the mixture is allowed to stand for 15 minutes. Then, under cooling with ice and stirring, the mixture is neutralized with 7.0 ml of 1N hydrochloric acid, whereupon white precipitate is obtained. The precipitate is recovered by filtration, rinsed with ethanol and ether and dried. By this procedure is obtained 620 mg of 2-sulfo-2-(2-imino-4-thiazolin-4-yl)acetic acid. IR(cm-1, KBr): 1732, 1628, 1603, 1576, 1230, 1190, 1050 NMR(NaHCO3 in D2Q, δ): 4.93(s,1H), 6.90(s,1H)
