1) Bis-[aryl-sulfonyl]-thiazolone-imide (2) reacts with methanol in the presence of guanidine carbonate to yield 3-methyl-thiazolone-aryl-sulfonylimide (2) as a chief product of the reaction.
2) Ethyl, allyl, n-butyl, isoamyl and benzyl alcohols, and ethylene glycol, have been found to react in a similar manner to give 3-alkylated 2-arylsulfonylaminothiazole.
3) It has been shown that guanidine carbonate catalyzes alkylation of acetosulfathiazole with arylsulfonyl ester to yield 3-alkylated derivatives.
4) A possible mechanism is suggested to account for these reactions.
