実験手順: Aniline (2.59 mL, 28.4 mmol) and NaI (4.06 g, 27.1 mmol) were added to a solution of 4-benzyl-2-chloromethyl-1,4-oxazepane (79) (6.49 g, 27.1 mmol) in n-butanol (68 mL, 0.4 M), and the reaction was heated to 110° C. until the reaction was judged complete by TLC (4 h). The reaction was cooled to room temperature, and water and CH2Cl2 were added. The organic layer was removed, and the aqueous layer was extracted with CH2Cl2 (2×). The combined organic extracts were dried over sodium sulfate, filtered and concentrated in vacuo to achieve (4-benzyl-1,4-oxazepan-2-ylmethyl)-phenyl amine 80, which was used without purification in the next reaction. 1H NMR (partial, CDCl3) 4.08-3.86 (3H, m), 3.80 (1H, d, J=13.3 Hz), 3.73 (1H, d, J=13.3 Hz), 3.22-3.05 (2H, m), 2.95-2.70 (3H, m), 2.64 (1H, dd, J=13.6, 7.6 Hz), 2.1-1.9 (2H, m) ppm. 13C NMR (CDCl3) 148.33, 139.38, 129.28, 129.11, 128.46, 127.23, 117.44, 113.13, 76.70, 67.49, 62.92, 59.35, 54.76, 46.93, 30.75 ppm.
