Hydrochloric Acid → HCID 58959882, compound

Participants

Reaction Steps

To a solution of 3.0 g of tert-butyl piperidin-4-ylcarbamate in 60 ml of methylene chloride, were added 2.5 ml of triethylamine, 2.4 g of HOBt, 1.3 g of hydroxyacetic acid and 3.5 g of WSCD hydrochloride, and the reaction mixture was stirred at room temperature for 18 hours. 1 M hydrochloric acid was added to the reaction mixture, and this was extracted with EtOAc. The organic layer was washed with aqueous saturated sodium hydrogencarbonate solution, water and brine. This was dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure. The resulting residue was purified with silica gel column chromatography (eluent: chloroform/MeOH=50/1) to obtain 2.8 g of tert-butyl [1-(hydroxyacetyl)piperidin-4-yl]carbamate.
