Reaction Steps

To a stirred solution of (2R)-1-chloro-3,3-dimethyl-1-oxobutan-2-yl acetate (0.247 g, 1.41 mmol) in CH2Cl2 (10 mL) was added triethylamine (0.39 mL, 2.83 mmol) and a solution of (S)-methyl-4-methylpiperazine-2-carboxylate (0.150 g, 0.943 mmol) in CH2Cl2 (3 mL) dropwise. The reaction mixture was stirred at room temperature for 30 minutes. Water (10 mL) was then added to quench the reaction and the reaction mixture was extracted with CH2Cl2 (2×25 mL). The combined organic layers were separated, washed with water (2×50 mL) dried over Na2SO4 and concentrated under reduced pressure to afford the title compound (0.12 g) as a white solid.
