Participants

Reaction Steps

N-tert-Butyl-3-(piperazin-1-ylmethyl)benzamide dihydrochloride (0.50 g, 1.44 mmol) was suspended in stirred dichloromethane (20 mL) at 0° C. (ice-bath) under an argon atmosphere. N-ethyl-N-isopropylpropan-2-amine (1.0 mL, 5.75 mmol) was added slowly. After 10 minutes stirring, the resulting solution was treated with a suspension of 4-nitrobenzoyl chloride (0.267 g, 1.44 mmol) In dichloromethane (10 ml). The ice-bath was removed and stirring continued for 1 hour. The solution was diluted with dichloromethane (70 mL) and washed with water (×4). The organic phase was dried on magnesium sulfate, filtered and concentrated under vacuum to give the title compound (0.58 g) as a yellow foam.
