1-Phenylpiperazine → HCID 68682718, compound

Participants

Reaction Steps

(5S,6S)-5-((benzyloxy)carbonyl)spiro(2,5)octane-6-carboxylic acid from step 7 (47 mg, 0.16 mmole) was dissolved in DMF (0.7 mL). To the solution, 1-phenylpiperazine (29 mg, 0.18 mmole) was added, followed by BOP (76 mg, 0.17 mmole). DIEA (53 mg, 0.41 mmole) was added after the mixture was stirred at r.t. for 10 min. The mixture was then stirred at r.t. overnight and quenched with sat'd NaHCO3 solution, extracted with EtOAc. The extract was washed with NaHCO3 sat'd solution, brine; dried over MgSO4. After filtration, the filtrate was concentrated. The resulting residue was purified by column chromatography to afford Benzyl (5S,6S)-6-((4-phenylpiperazin-1-yl)carbonyl)spiro(2.5) octane-5-carboxylate.
