실험 절차

4-Trifluoromethanesulfonylamino-butyric acid methyl ester (0.42 g, 1.77 mmol) [example 212, step a] was taken up in methanol [2 mL] and 1N NaOH was added [2.66 mL] and stirred for 2 hours. 1N HCl was added and the product was extracted with ethyl acetate, dried with magnesium sulfate and evaporated. The crude product (0.13 g, 0.57 mmol) was dissolved in dichloromethane/DMF [1 mL/1 drop] and thionyl chloride (0.08 mL, 1.14 was added. The reaction was stirred at room temperature for 2 hours and then evaporated and used directly in the next step.
