3,5-DIMETHOXYPYRIDINE-4-CARBOXALDEHYDE Use and Manufacturing
To a solution of 3, 5-dimethoxypyridine (3.6 g, 25.90 mmol, 1 eq.) in THF (80 mL) was added BuLi (3Mhexanes, 13.0 mL, 38.85 mmol, 1.5 eq.) at-20 °C. The mixture was warmed to 0 °C, stirred at 0 °C for 30 mm, cooled back down to -78 °C, and added DMF (3.8 g, 51.8 mmol, 2 eq.). The mixture was gradually warmed to 0 °C, quenched with NH4C1(saL) solution, and diluted with EtOAc. The aqueous layer was extracted with EtOAc twice. The combined organic layers were washed with brine, dried over Na2SO4, concentrated, and purified on silica gel using a mixture of EtOAc and hexanes as eluent to give 3 , 5-dimethoxyisonicotinaldehyde (2.7 g, 62percent) as a yellow solid. LRMS (M+HStep 2 To a stirred solution of lithium diisopropylamide (LDA, 1.2 mmol) in THF (4 mL) at -78
