Procedure
2-Fluoro-4-hydroxy-5-methoxy-benzaldehyde (0.500 g, 2.94 mmol) was dissolved in DMF (2.6 mL) containing Cs2CO3 (2.88 g, 8.82 mmol). 1-Bromo-2-methoxy-ethane (1.23 g, 828 μL, 8.82 mmol) was added and the reaction mixture was allowed to stir for 86 h. The reaction mixture was filtered and the filtrate was evaporated to dryness to give 2-fluoro-5-methoxy-4-(2-methoxyethoxy)benzaldehyde. ESI-MS m/z calc. 228.1. found 229.0 (M+1)+. Retention time: 1.14 minutes (3 min run).
