Participants

Reaction Steps

(S)-4-methyl-2, 5-oxazolidinedione (L-alanine-NCA) (345 mg, 3 mmol) was dissolved in ethyl acetate (20 mL), followed by the addition of decanoyl chloride (744 mg, 3.9 mmol) under ice cooling. Further, a solution of N-methylmorpholine (394 mg, 3.9 mmol) in ethyl acetate (10 mL) was added dropwise under ice cooling over 20 minutes, and the resulting mixture was then stirred at the same temperature for 2 hours, the reaction mixture was treated in a similar manner as in Synthesis Process 5 of Example 8 to afford the title compound (525 mg, 65%) as a colorless clear syrup. A portion of the thus-obtained syrup was recrystallized from hexane to obtain white crystals (280 mg).
