Reaction Steps

To a solution of tert-butyl 4-{4-[(hydroxyimino)methyl]-1,3-thiazol-2-yl}piperidine-1-carboxylate (2.90 g) and 1-(cyclohexylmethoxy)-2-vinylbenzene (2.40 g) in ethyl acetate (300 ml) were added, at room temperature, potassium hydrogencarbonate (4.60 g) and N-chlorosuccinimide (1.48 g), and then one drop of water. The reaction mixture was stirred at 60° C. for 6 h, then admixed with ethyl acetate and water and extracted with ethyl acetate. The organic extracts were dried over sodium sulphate and concentrated under reduced pressure. The residue was purified by chromatography. This gave tert-butyl 4-(4-{5-[2-(cyclohexylmethoxy)phenyl]-4,5-dihydro-1,2-oxazol-3-yl}-1,3-thiazol-2-yl)piperidine-1-carboxylate (3.40 g).
