Reaction Steps

100 mg (0.26 mmol) of tert-butyl((3,4-difluorophenyl)sulfonyl)(thiazol-2-yl)carbamate was dissolved in 5 mL of tetrahydrofuran under nitrogen gas, and cooled to −78° C. After adding 0.25 mL (0.39 mmol) of n-butyllithium (1.6M in tetrahydrofuran) slowly, the mixture was stirred for 30 minutes as maintaining −78° C. 23 mg (0.13 mmol) of 2-(furan-3-yl)nicotinaldehyde was dissolved in 0.5 mL of tetrahydrofuran, and added to the above reacting solution. As warming from −78° C. to room temperature, the reacting solution was stirred for 24 hours. Ethyl acetate and water/1 N-hydrochloride were added to the reacting solution, and it was stirred. After separating layers, the organic layer only was collected and concentrated under reduced pressure. The obtained residue was separated by column chromatography (developing solvent, hexane:ethyl acetate=1:1) to obtain 7 mg (6.1% yield) of the title compound.
