Water → 1-(4-Formylbenzoyl)-4-isopropylpiperazine

Participants

Reaction Steps

A solution of 4-formyl-benzoyl chloride (2.80, 16.65 mol) (prepared as in Example 1 above) in toluene (43.3 g, 469.39 mmol) was added slowly to a solution of NaHCO3 (0.8 g, 9.52 mmol) and 4-isopropylpiperazine (2.50 g, 18.35 mmol) in water (5 g, 277 mmol) at 0° C. The reaction mixture was vigorously stirred until the reaction was deemed complete. The layers were split and the toluene phase was concentrated to yield the title compound as a yellow oil.
