Reaction Steps

1-Methyl-piperazine (1.23 g; 12.3 mmol; 5 eq.) was added to a solution of bromo-difluoro-acetic acid ethyl ester (500 mg; 2.46 mmol; 1 eq.) in THF (50 mL) and the reaction mixture was stirred at room temperature for 16 hours then concentrated in vacuo. The residue was taken up in EA, washed with water, dried over magnesium sulfate and concentrated in vacuo to afford the title compound (450 mg, 71%) as a yellow oil.
