Reaction Steps
A solution of 1-(5-trifluoromethyl-pyridin-2-yl)-piperazine (2.77 g, 11.99 mmoles) in DCM (42 mL) and TEA (4.2 mL) was treated with (2S)-2-bromo-propionic acid (1.19 mL, 13.2 mmoles) and stirred overnight at 35° C. The DCM was removed under reduced pressure to provide crude title compound.
