2-Aminothiazole → tert-butyl N-[(2-methylpropan-2-yl)oxycarbonyl]-N-(1,3-thiazol-2-yl)carbamate

Participants

Reaction Steps

A solution of 2-aminothiazole (5 g, 0.05 mol), (2-methylpropan-2-yl)oxycarbonyl tert-butyl carbonate (27.8 g, 0.15 mol) and DMAP (100 mg) in THF (100 mL) was stirred at reflux overnight. The mixture was allowed to cool and concentrated in vacuo. The residue was chromatographed on silica, eluting with 8% ethyl acetate in hexane, to give the desired material as a white solid (12 g).
