1-Azepanylacetonitrile (290). Azepane (289) (4.9 ml_, 43.8 mmol) was added dropwise to a stirred aqueous solution of glycolonitrile (55%, 5.0 g, 48.2 mmol) at 5 0C and the solution was stirred at 70 0C for 30 min. The solution was cooled, diluted with water (20 mL), washed with Et2O (3 x 50 ml_). The organic fraction was dried and the solvent evaporated to give nitrile 290 (5.58 g, 92%) as a colourless oil: 1H NMR δ 3.56 (s, 2 H, CH2CN), 2.71 (br dd, J = 5.8, 5.5 Hz, 4 H, 2 x CH2N), 1.67-1.73 (m, 4 H, 2 x CH2), 1.59- 1.64 (m, 4 H, 2 x CH2).
