Triethylamine → 1-[4-(2-Chloro-4-nitrophenyl)piperazin-1-yl]-2-methylpropan-1-one

Participants

Reaction Steps

According to Scheme 4 Step 1: Isobutyryl chloride (1.24 mmol, 0.13 mL) and Et3N (2.48 mmol, 0.35 mL) were added to a solution of 1-(2-chloro-4-nitrophenyl)piperazine (0.83 mmol, 200 mg) in DCM (5 mL) at 0° C. The reaction mixture was stirred at room temperature for 2 hours. The organic phase was washed with a saturated solution of NaHCO3. The aqueous phase was extracted with AcOEt. The organic phase was washed with brine, was dried over Na2SO4, was filtered and was concentrated under reduced pressure to afford 1-(4-(2-chloro-4-nitrophenyl)piperazin-1-yl)-2-methylpropan-1-one (0.83 mmol, 261 mg, 100%). The product was used without further purification.
