Procedure

To a solution of 1-[2,4-bis(trifluoromethyl)benzyl]piperidine-4-carbaldehyde (941 mg) in 2-propanol (20 mL) were added 1,5-anhydro-2,4-dideoxy-2-[(2-oxo-2,5-dihydro-1,3-thiazol-4-yl)amino]-threo-pentitol (900 mg) and piperidinium acetate (411 mg). The reaction mixture was stirred at 75° C. overnight, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) and silica gel column chromatography (NH, methanol/ethyl acetate) to give the title compound (806 mg). Absolute configuration undetermined.
