Reaction Steps
To a solution of (S)-tert-butyl 3-(aminomethyl)piperidine-1-carboxylate (500 mg, 2.33 mmol) in CH2Cl2 at −10° C. was added triethylamine (650 μL, 4.66 mmol) followed by the dropwise addition of 2-methoxyethyl chloroformate (325 μL, 2.79 mmol). The reaction was warmed to room temperature and quenched with water. The aqueous layer was extracted with CH2Cl2, and the combined extracts were dried over MgSO4, filtered, and evaporated. Purification via silica gel chromatography using 0 to 10% EtOAc in CH2Cl2 afforded 2-methoxyethyl((S)-1-(tert-butoxycarbonyl)piperidin-3-yl)methylcarbamate (496 mg, 67%). LC/MS: m/z 317.3 (M+H)+ at 2.56 min (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)).
