Procedure

A mixture of 5-bromothiazol-2-amine (3.0 g, 11.5 mmol), adamantane-1-carbonyl chloride (2.74 g, 13.8 mmol), triethylamine (3.2 mL, 23 mmol) and 4-di(methylamino)pyridine (1.1 g) in tetrahydrofuran (100 mL) was heated at 80° C. for 48 hours. The mixture was cooled to ambient temperature, concentrated, diluted with water and extracted with ethyl acetate. The organic extract was dried (Na2SO4), filtered and concentrated. Purification by flash chromatography (silica gel, 25% ethyl acetate/hexanes) afforded the title compound, MS (ESI) m/z 342 (M+H)+
