Sodium Cyanide → HCID 66998544, 화합물

4-(4-Fluoro-5,6,7,8-tetrahydro-naphthalene-1-sulfonylamino)-piperidine-1-carboxylic acid tert-butyl ester (970 mg, 2.35 mmol) was dissolved in DMSO (10 mL) and sodium cyanide (577 mg, 11.77 mmol) was added. The mixture was heated overnight at 100° C. An additional 5 equivalents of sodium cyanide (577 mg, 11.77 mmol) were added and the reaction was stirred overnight at 100° C. The reaction was cooled to room temperature and diluted with dichloromethane (100 mL). The mixture was charged to a separatory funnel and extracted three times with water, brine and then dried over MgSO4. Filtration and concentration in vacuo afforded a brown color foam that was triturated with EtOAc to afford a tan solid.
