76% | With caesium carbonate; In acetonitrile; | To a stirred solution of 2-(2-(bromomethyl)-4-fluorophenyl)-5-methylthiophene (0.200g, 1.625 mM) and 5-hydroxypicolinaldehyde (0.435g, 1.625) in dry acetonitrile, cesium carbonate (0.794g, 2.43 mM) was added and stirred overnight. The mixture was filtered and residue was washed with acetonitrile. The filtrate was concentrated to give 5-((2- bromo-5- fluorobenzyl)oxy)picolinaldehyde. Yield: 0.38 g, 76percent; JH NMR (300 MHz, DMSO-d6) delta: delta 9.90 (s, 1H), 8.62-8.61 (d, / = 8.7 Hz, 1H), 7.99-7.96 (d, / = 9.3Hz,lH),7.77- 7.70 (m, 2H), 7.57-7.53 (dd, / = 3, 9.3 Hz, 1H), 7.28-7.22 (m,lH),5.31 (s,2H); MS (E/Z): 311.9 (M + 1). |
