Procedure

To a mixture of 4-hydroxybenzonitrile (665 mg, 5.59 mmol) and caesium carbonate (2.00 g, 6.14 mmol) in DMF (5 mL) was added 4-(bromomethyl)tetrahydro-2H-pyran (1.00 g, 5.59 mmol), and the reaction mixture was stirred at 80° C. over night. After cooling to rt, the reaction mixture was poured into water. After stirring for a few minutes, the precipitate was collected by filtration, washed with water and dried in vacuo to give the title compound (785 mg, 65%): 1H NMR (400 MHz, CDCl3) δ 7.58 (d, 2H), 7.92 (d, 2H), 4.05-4.00 (dd, 2H), 3.82 (d, 2H), 3.48-3.41 (m, 2H), 2.15-2.02 (m, 1H), 1.78-1.72 (dd, 2H), 1.52-1.41 (m, 2H); ES-MS m/z 218, HPLC RT (Method D) 2.09 min.
