6.91 g (75.0 mmol) potassium carbonate was added to a solution of 1.35 ml (15.0 mmol) 2-bromothiazole and 3.00 g (15.0 mmol) piperidin-4-yl-carbamic acid-tert-butyl ester in DMF (50 ml) and heated to 120° C. for 8 h. Subsequently, the solvent was removed in vacuo and the residue taken up by chloroform. This solution was washed with water and brine in turn, dried over MgSO4, filtered and concentrated in vacuo. Column chromatography (SiO2, chloroform) was carried out on the residue, yielding 1.14 g (4.0 mmol, 27%) (1-thiazol-2-yl-piperidin-4-yl)-carbamic acid-tert-butyl ester.
