Potassium Carbonate → HCID 58424876, compound

Participants

Reaction Steps

The compound (60 mg, 0.28 mmol) prepared in step 2 and potassium carbonate (120 mg, 0.85 mmol) were dissolved in acetonitrile (6 ml)/N,N-dimethylformamide (3 ml), added with t-butyl 4-(methylsulfonyloxy)piperidine-1-carboxylate (240 mg, 0.85 mmol). The resulting mixture was stirred for 3 days at 100˜110° C. and cooled to room temperature. After extraction with chloroform, the reaction mixture was washed with brine and dried over anhydrous sodium sulfate. The solvent was removed under reduced pressure and the residue was purified by flash column chromatography (chloroform:methanol=10:1) to obtain the title compound (65 mg, yield: 58%, white solid).
