Reaktionsschritte

To a solution of 4-fluoro-2-hydroxy-benzaldehyde (560 mg, 4 mmol) in DMF (10 ml) were added benzyl chloride (0.5 ml, 4.33 mmol), and K2CO3 (860 mg, 6.22 mmol). After heating at reflux for an hour, the reaction mixture was allowed to cool to room temperature and was poured into a mixture of EtOAc/H2O. The organic layer was separated, washed with H2O and dried over MgSO4. The resulting oil was purified by flash chromatography to give 2-benzyloxy-4-fluoro-benzaldehyde as pale oil (628 mg, 68%), 1H NMR (CDCl3, 300 MHz) δ: 5.17 (s, 2H), 6.74 (m, 2H), 7.36 (m, 5H), 7.88 (m, 1H), 10.51 (s, 1H).
