Procedure
4-amino-1-butanol (15.0 g, 168.27 mmol) and methyl trifluoroacetate (82.96 mL, 824.55 mmol) were combined in methanol (250 mL) and heated at reflux for 2 hours. The reaction was concentrated to yield the title compound (26.6 g, 85.4%) as a clear oil which had the following properties: 1H NMR CDCl3 δ: 7.08 (brd s, 1H), 3.71 (t, J=5.4 Hz, 2H), 3.40 (q, J=6.2 and 6.2 Hz, 2H), 1.75-1.61 (m, 4H).
