   DryingHCl (2×50 ml) and 1 N--NaOH (2×50 ml), dried (MgSO4)
3. 3
   Otherevaporated in vacuo

Procedure

Cyclohexanecarbonyl chloride (4.38 g, 30 mmol) was added dropwise to a solution of 2-aminothiazole (3.00 g, 30 mmol) and di-isopropylethylamine (3.87 g, 30 mmol) in dichloromethane (50 ml) at 0° C. The mixture was warmed to room temperature, stirred for 18 h, washed with 1 N--HCl (2×50 ml) and 1 N--NaOH (2×50 ml), dried (MgSO4), and evaporated in vacuo to give the product (4.59 g) as white crystals.
