Reaction Steps
In N,N-dimethylformamide (50 ml) was dissolved 1-[(6-chloronaphthalen-2-yl)sulfonyl]-4-[(4,5,6,7-tetrahydrothiazolo[5,4-c]pyridin-2-yl)carbonyl]piperazine hydrochloride (240 mg), followed by the addition of triethylamine (0.28 ml) and then tert-butyl bromoacetate (0.14 ml). The resulting mixture was stirred overnight at room temperature. After concentration of the reaction mixture under reduced pressure, ethyl acetate was added to the residue. The resulting mixture was washed with water, dried over anhydrous sodium sulfate and distilled under reduced pressure to remove the solvent. The residue was purified by chromatography on a silica gel column (Φ3.0×12.0 cm, hexane:ethyl acetate 3:2), whereby the title compound (207 mg) was obtained as a colorless foam.
