ω-aminocaproic acid (2.59 g, 19.7 mol) was dissolved in 100 mL methanol, and triethylamine (4.2 mL, 29.9 mmol) and ethyl trifluoroacetate (3.5 mL, 29.5 mmol) were added and agitated for a day and night at room temperature. The reaction solution was poured into 1% by weight hydrochloric acid (100 mL), and extracted once with methylene chloride. The methylene chloride layer was washed once with water and once with a saturated aqueous sodium chloride solution, and then dried and concentrated with anhydrous sodium sulfate to obtain 2.78 g of a crude product.
