Participants

Reaction Steps

L-Phenylalanine methyl ester hydrochloride (259 mg, 1.2 mmol) was suspended in tetrahydrofuran (6 mL), followed by the addition of N-methylmorpholine (121 mg, 1.2 mmol) at 0° C. The resulting mixture was stirred for 20 minutes. (S)-3-Decanoyl-4-methyl-2,5-oxazolidinedione (N-decanoyl-L-alanine-NCA) (270 mg, 1 mmol) was added as crystals at 0° C., followed by stirring for 5 minutes. The mixture was allowed to rise in temperature to room temperature, at which the mixture was stirred for 30 minutes. The reaction mixture was treated in a similar manner as in Example 19 to afford the title compound (289 mg, 71%) as white crystals.
