[(2S)-piperidin-2-yl]methanol;hydrochloride

反応条件: temp:2.51; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a solution of (S)-1-Piperidin-2-yl-methanol hydrochloride (3.43 g, 22.63 mmol), imidazole (6.1 g, 88.72 mmol) and triethylamine (7.33 g, 72.42 mmol) in anhydrous dichloromethane (120 mL) at 0-5° C. was added a solution of thionyl chloride (3.2 g, 25.86 mmol) in anhydrous dichloromethane (10 mL) over a period of 45 min. The reaction mixture was stirred at 0-5° C. for 45 min, partitioned with H2O and the aqueous layer was extracted with dichloromethane (2×150 mL). The combined organic layer was washed with H2O, dried over Na2SO4, and concentrated in vacuo to give an orange liquid. Flash column chromatography purification (silica gel, 2% EtOAc in dichloromethane) afforded the title product as a clear, colorless liquid (1.31 g, 36%). partitioned with H2O the aqueous layer was extracted with dichloromethane (2×150 mL) The combined organic layer was washed with H2O dried over Na2SO4 concentrated in vacuo to give an orange liquid Flash column chromatography purification (silica gel, 2% EtOAc in dichloromethane)

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: A 4M HCl solution in dioxane (30 mL) was added to (S)-2-Hydroxymethyl-piperidine-1-carboxylic acid tert-butyl ester (5.12 g, 23.78 mmol). The mixture was stirred at rt for 3 h. The solvent was removed in vacuo to yield the title product as a hydrochloride salt (3.43 g, 95%). The solvent was removed in vacuo
