1-Piperidinecarbonyl chloride → HCID 66815991, compound

Participants

Reaction Steps

TEA (1.143 mmol, 3 eq) and piperidine-1-carbonyl chloride (0.457 mmol, 1.2 eq) were sequentially added to a mixed solution of 8-(3-chloro-benzenesulfonyl)-2-piperidin-3-yl-1,3,8-triaza-spiro[4.5]dec-1-en-4-one trifluoroacetate (200 mg, 0.38 mmol) in dichloromethane (3 ml). The resulting mixture was stirred at room temperature overnight and then concentrated under reduced pressure. The resulting residue was purified by HPLC to give 8-(3-chloro-benzenesulfonyl)-2-[1-(piperidine-1-carbonyl)-piperidin-3-yl]-1,3,8-triaza-spiro[4.5]dec-1-en-4-one (30 mg, yield 15%).
