To a stirred solution of 4-(bromomethyl)-3-chlorobenzaldehyde (3.8 g, 14 mmol) in DMF (40 mL) was added potassium pthalimide (3.54 g, 19.14 mmol), and the mixture was heated at 60° C. for 6 h. The reaction mixture was cooled to ambient temperature and diluted with H2O (100 mL). The solid obtained was separated by filtration and dried under vacuum to afford the title compound as a white solid (2.8 g, 60%): mp 123-126° C.; 1H NMR (400 MHz, CDCl3) δ 9.95 (s, 1H), 8.21 (s, 1H), 7.91 (m, 3H), 7.80 (m, 2H), 7.20 (m, 1H), 5.05 (s, 2H); ESIMS m/z 298.03 ([M−H]−).
