Reaction Steps

To a solution of dry EtOH (65 mL) and acetyl chloride (6.52 mL added dropwise at 0° C.) was added (2S, 4S)-4-methyl pipecolic acid (2.8 g, 19.6 mmol) at room temperature. The reaction was stirred at room temperature for 16 hrs and then concentrated in vacuo to give the title compound, (3.01 g, 90%).
