Reaction Steps

A mixture of 4-fluorobenzaldehyde (0.242 g, 1.95 mmol), 1-isopropylpiperazine (0.335 mL, 2.34 mmol), and K2CO3 (0.323 g, 2.34 mmol) in DMF (2.44 mL) was heated at 120° C. overnight. The mixture was diluted with EtOAc (200 mL), washed with 10% aqueous LiCl (3×75 mL) and brine (75 mL), dried over Na2SO4, and filtered. The volatiles were removed under vacuum to yield 4-(4-Isopropylpiperazin-1-yl)benzaldehyde (0.504 g) as an orange solid, which was used without further purification.
