실험 절차

Methyl trifluoroacetate (513 μL, 5.10 mmoles) and triethylamine (474 μL, 3.40 mmoles) were added to a suspension of aminocaproic acid (455 mg, 3.40 mmoles) in methanol (2 mL). After the mixture was stirred vigorously for 8 h, 1 N HCl was added dropwise until the a pH of 2 was obtained. The reaction was added to ethyl acetate (10 mL) was washed with 1 N HCl (2×2 mL), dried over MgSO4, and concentrated in vacuo to yield the amide as a white solid (745 mg, 3.49 mmoles, quant.). LRMS: not performed. 1H NMR: spectrum is consistent with the predicted structure.
