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).
