2-Aminothiazole → 4-Acetylamino-naphthalene-1-sulfonic acid thiazol-2-ylamide

Participants

Reaction Steps

To a solution of 4-acetamidonaphthalene-1-sulfonyl chloride (3.69 g, 2.42 mmol) and pyridine (2 ml) was added 2-aminothiazole (0.24 g, 2.42 mmol). This mixture was stirred at RT for 72 h. Purification via silica gel chromatography (first using 2% MeOH in CH2Cl2 to wash out remaining amine, then using 8% MeOH in CH2Cl2) gave N-[4-(thiazol-2-ylsulfamoyl)-naphthalen-1-yl]acetamide (0.48 g, 57%). LC/MS (10-99% CH3CN), M/Z: M+1 obs=348.10; tR=1.78 min.
