실험 절차

To a solution of propane-1-sulfonic acid cyclopropyl-(2-hydroxy-ethyl)-amide (150 mg, 0.8 mmol) in CH2Cl2 and DMAP (97 mg, 0.8 mmol) was added dropwise a solution of propane-1-sulfonyl chloride (97 mg, 0.8 mmol) in CH2Cl2. The resulting mixture was stirred at room temperature over night, diluted with 50 ml of CH2Cl2, extracted subsequently with water, 1 M HCl, and brine, tried over Na2SO4, filtered and the solvent evaporated to obtain 197.5 mg of product which was used in the next step without further purification.
