Reaction Steps

To a suspension of sodium hydride (60% dispersion in mineral oil; 490 mg, 12.2 mmol) in THF (10 mL) was added a solution of tetrahydro-2H-pyran-4-ol (1.20 g, 12.2 mmol) in THF (2 mL) at rt. The reaction mixture was stirred at it for several minutes and then heated to reflux for 15 min. After cooling to rt, 4-(bromomethyl)benzonitrile (2.00 g, 10.2 mmol) was added, and the reaction mixture was stirred at it over night. Ethyl acetate was added and the mixture was washed with water. The organic layer was dried with anhydrous magnesium sulfate and filtered. After evaporation of the solvent, the crude product was purified by MPLC (silica, cyclohexane/ethyl acetate 7:3) to afford the title compound (1.57 g, 71%): 1H NMR (400 MHz, CDCl3) δ 7.53 (d, 2H), 7.45 (d, 2H), 4.61 (s, 2H), 4.00-3.92 (m, 2H), 3.65-3.58 (m, 1H), 3.49-3.41 (m, 2H), 1.99-1.92 (m, 2H), 1.72-1.62 (m, 2H); ES-MS m/z 218, HPLC RT (Method D) 1.86 min.
