To a mixture of 4-(bromoethyl)benzaldehyde (0.200 g, 1.0 mmol) and K2CO3 (0.277 g, 2.0 mmol) in DMF (5 mL) was added N-isopropylpiperazine (0.129 g, 1.0 mmol) and the reaction was stirred at room temperature for 5 hours, then concentrated in vacuo. The resulting mixture was diluted with H2O and extracted with EtOAc. The organics were washed with brine, dried over anhydrous Na2SO4, filtered, and concentrated in vacuo to afford 4-((4-Isopropylpiperazin-1-yl)methyl)benzaldehyde (0.240 g, 97%).
