Triethylamine → Tert-butyl 4-(2-(4-chlorophenoxy)acetyl)piperazine-1-carboxylate

Participants

Reaction Steps

To a solution of tert-butyl piperazine-1-carboxylate (0.30 g, 0.16 mmol) and triethylamine (0.34 ml, 2.42 mmol) in dichloromethane (8 ml) was added p-chlorophenoxyacetyl chloride (0.36 mg, 1.77 mmol). The reaction mixture was stirred at room temperature overnight. The mixture was diluted with dichloromethane and washed with water, brine and dried over Na2SO4. After removing the solvents, the crude residue was purified by chromatography on silica gel (CH2Cl2/MeOH 80:1) to yield the title compound as a white solid (0.57 g, 100%).
