Reaction Steps

Triethylamine (976 mg, 9.66 mmol) was added to a solution of 1-(4-nitrophenyl)piperazine (1.00 g, 4.83 mmol) in dichloromethane (20 mL) at 0° C. and stirred for 30 min. Isobutyryl chloride (617 mg, 5.79 mmol) was then added and the mixture was warmed to ambient temperature and stirred for 4 h. the reaction mixture was quenched with ice-water and the organic layer separated. The aqueous layer was extracted with dichloromethane (5×5 mL) and the combined organic layers were washed water, saturated sodium bicarbonate solution, brine, dried over anhydrous sodium sulphate and concentrated in vacuo to afford 2-methyl-1-[4-(4-nitrophenyl)piperazin-1-yl]propan-1-one (1.20 g, 90%) as a yellow solid.
