The reaction of aminomethansulfonic acid (I) with phthalic anhydride (II) by means of potassium acetate in refluxing acetic acid gives phthalimidomethansulfonic acid (III), which by reaction with PCl5 in refluxing benzene is converted into its acyl chloride (IV). The condensation of (IV) with tert-butylamine (A) in CHCl3 affords N-tert-butylphthalimidomethansulfonamide (V), which by reaction with hydrazine hydrate in refluxing ethanol yields 2-aminomethan-N-tert-butylsulfonamide (VI). The reaction of (VI) with CS2 and MeI by means of triethylamine in ethanol gives N-tert-butylsulfamoylmethyldithiocarbamic acid methyl ester (VII), which is cyclized with NaN3 in hot water to afford 1-(N-tert-butylsulfamoylmethyl)tetrazol-5-thiol (VIII). The hydrolysis of (VIII) with trifluoroacetic acid yields compound 1-sulfamoylmethyltetrazol-5-thiol (IX).
