Reaction Steps

A mixture of 4-fluorobenzaldehyde (2.0 g, 16.1 mmol), 2,6-dimethylpiperazine (2.2 g, 19.3 mmol), and K2CO3 (2.7 g, 19.3 mmol) in DMF (10 mL) was heated at 120° C. for 4 hours. Then, the reaction was diluted with H2O and extracted with EtOAc. The organics were washed with brine, dried (Na2SO4), filtered and concentrated in vacuo. Purification by flash chromatography on silica gel eluting with 3% to 10% MeOH/CH2Cl2 afforded 4-(3,5-dimethylpiperazin-1-yl)benzaldehyde (2.0 g, 57%).
