Komponenten

Versuchsvorschrift

To a suspension of sodium hydride (80% dispersed in oil, 876 mg, 29.2 mmol) in DMSO (10 ml) was added benzyl alcohol (3 ml, 29.2 mmol) and the mixture stirred at room temperature for 1 hour. To this was added 4-chloropyridine (3.3 g, 29.2 mmol) and the reaction stirred at room temperature overnight. The precipitated sodium chloride was removed by filtration and the filtrate diluted with water (100 ml) and extracted with ether (3×120 ml). The combined organic layers were dried (MgSO4) and evaporated in vacuo to yield the title compound as an oil (4.8 g, 95%); δH (CDCl3) 5.11 (2H, s, PhCH2O), 6.87 (2H, d, J 6.3 Hz, 3-H, 5-H), 7.29-7.42 (5H, m, Ph), and 8.42 (2H, d, J 6.3 Hz, 2-H, 6-H).
