Procedure
Prepared as described in General Procedure 2. To chlorocarbonyl isocyanate (0.2 g) in tetrahydrofuran at −20-0° C. was added dicyclohexylamine (1 equivalent) and triethylamine (0.27 mL). After 20 min 2-aminothiazole (0.2 g) was added and the reaction allowed to warm to room temperature over 3 h and stirred overnight at room temperature. The reaction mixture was partially concentrated. The crude product was then dissolved in tetrahydrofuran and purified by flash chromatography (Eluant 20 dichloromethane:1 methanol).
