الإجراء التجريبي

To a solution of 3 g (19.0 mmol) of ethyl N-piperazinecarboxylate in 25 mL of CH3CN was added 1.57 g (1.32 mL 20.1 mmol) of 2-chloroacetonitrile and 15.6 g (95 mmol) K2CO3.1½H2O. The suspension was stirred at room temperature for 16 hours. The reaction was analyzed using TLC (35% Ethyl acetate/Hexanes, product r.f. 0.38 vs. s.m. r.f. of 0.02). The analysis indicated the reaction was complete. The golden yellow solution was evaporated to dryness. The residue was extracted with CH2Cl2/H2O, dried with MgSO4, and concentrated.
