Participants

Reaction Steps

To a solution of 1-ethylpiperazine (1 g, 8.771 mmol, 1.0 eq) in DMF were added K2CO3 (3 g, 21.927 mmol, 2.5 eq.) and ethyl 2-bromoacetate (2.19 g, 13.156 mmol, 1.5 eq.). The mixture was stirred at RT for 16 h. The mixture was quenched and extracted as in Intermediate Example 5(a). The solvent was distilled off to afford the product in 76.4% yield (1.3 g).
