Reaction Steps

Step A) Preparation of N-(tert-butyl)-1-methyl-1H-imidazole-4-sulfonamide: A solution of 5.2 gm (29 mmol) 1-methyl-1H-imidazole-4-sulfonyl chloride in 30 mL THF was cooled in ice water while 7 mL tert-butylamine was added dropwise. The solution was warmed to room temperature and stirred overnight. Solids were filtered and rinsed with additional THF. The filtrate was concentrated to give a white solid that was recrystallized from water and dried in vacuo to give 4.8 gm of the subtitle compound, 1H NMR (d6-DMSO) δ 7.75 (s, 1H), 7.65 (s, 1H), 7.2 (s, 1H), 3.7 (s, 3H), 1.1 (s, 9H).
