Reaktionsschritte
A solution of 2,6-pyridinedimethanol (5.0 g, 35.9 mmol) in DMF (30 mL) at 0° C. was treated with sodium hydride (1.44 g, 35.9 mmol), stirred for 30 min, treated with allyl bromide (3.42 ml, 39.5 mmol), stirred for 16 h at room temperature, poured into water (150 mL), extracted with EtOAc (3×30 mL) and the combined organic phase was dried (MgSO4), concentrated in vacuo and purified by chromatography [SiO2; isohexane:EtOAc (3:1 to 1:1)] to give the title compound (1.56 g, 24%) as a colourless oil: NMR δH (400 MHz, CDCl3) 7.69 (1H, t, J 7.5 Hz), 7.37 (1H, d, J 7.5 Hz), 7.13 (1H, d, J 7.5 Hz), 6.04-5.93 (1H, m), 5.38-5.21 (2H, m), 4.74 (2H, d, J 5.0 Hz), 4.65 (2H, s), 4.15-4.09 (2H, m) and 3.76 (1H, t, J 5.0 Hz).
