Reaction Steps
To a solution of 1-methylpiperazine (1 g, 8.771 mmol, 1.0 eq) in DMF were added K2CO3 (265 m g, 21.927 mmol, 2.5 eq) and ethyl 2-bromoacetate (167 mg, 13.15 mmol, 1.5 eq). The mixture was stirred at RT for 16 h and 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).
