실험 절차

To a solution of 1.96 g (7.39 mmol) of 4-(2-(tert-butoxycarbonylamino)ethyl)benzoic acid in 25 mL, of DMF was added 4.43 g (32.1 mmol) of potassium carbonate and 3.00 mL (37.2 mmol) of iodoethane at 0° C. The mixture was warmed to 22° C. and stirred for about 16 h. The reaction was then diluted with 20 ml, of water and 100 mL of saturated NaHCO3. The mixture was extracted with DCM (3×200 mL) and the combined organics were washed with 100 mL of water, dried (MgSO4) and evaporated to give ethyl 4-(2-(tert-butoxycarbonylamino)ethyl)benzoate as a sticky off-white solid.
