Steps:

N2-Methyl-L-leucinamide (10)
To a solution of N-methyl-L-leucine (5.00 g, 34.4 mmol) in methanol (140 ml) was added thionyl chloride (7.82 ml, 103 mmol) at 0 °C. After being stirred at room temperature for 16 h, the reaction mixture was concentrated in vacuo to give crude methyl ester hydrochloride (6.85 g) as white solids.
