실험 절차

To a solution of methanesulfonic acid 2-tert-butoxycarbonylamino-propyl ester (23 mmol) in CH3CN (20 mL) was added morpholine (28 mmol) and K2CO3 (23 mmol) at room temperature. The reaction mixture was brought to 50° C. and kept at the same temperature overnight. The reaction mixture was cooled and solvent was removed under reduced pressure, and the residue was treated with CH2Cl2 (50 mL) and H2O (50 mL). The organic layer was separated and the aqueous layer was extracted with CH2Cl2. The combined organic layer was dried over Na2SO4. Solvent was removed under reduced pressure and the residue was purified by column chromatography (ethyl acetate) to afford (1-methyl-2-morpholin-4-yl-ethyl)-carbamic acid tert-butyl ester as viscous liquid, yield: 62%. MS (M+H)=245.
