The N′-methyl-N-2-chloroethylpiperazine dihydrochloride (10.0 g, 45.4 mmol) was added slowly to a mixture of 50% aqueous potassium carbonate (200 mL) and ether (200 mL) and the mixture was stirred for 30 min., layers were separated, aqueous layer extracted with ether ( 2×200 mL). Combined organic extracts were dried on anhydrous sodium sulfate and concentrated to give N′-methyl-N-2-chloroethylpiperazine (6.2 g).
