実験手順
A solution of 2.53 g of benzyl chloride (20 mmol), 1.86 g of 4-picoline (20 mmol) and 20 mL of acetonitrile was refluxed for three hours, cooled to room temperature and then frozen in refrigerator. Pale pink crystals precipitated from the solution, which were collected by filtration and washed with ether (3×5 mL) to afford 4.09 g of the product (92% yield). 1HNMR (DMSO-d6, 400 MHz): δ 9.1 (s, 2H), 8.0 (d, 2H, J=6.24), 7.5 (s, 2H), 7.4 (m, 3H), 5.8 (s, 2H), 2.6 (s, 3h); 13C NMR (DMSO-d6, 100 MHz): δ 159.0, 143.5, 134.3, 128.9, 128.8, 128.3, 61.9, 21.1.
