Reaction Steps

(S)-3-Benzoyl-4-tert-butyl-2,5-oxazolidinedione (N-benzoyl-L-tert-leucine-NCA)(100 mg, 0.38 mmol) was dissolved in ethyl acetate (2.0 mL), followed by the addition of a solution of (S)-1-(p-tolyl)ethylamine (52 mg, 0.38 mmol) in ethyl acetate (2.0 mL) at 0° C. The resulting mixture was stirred for 30 minutes. The reaction mixture was poured into 1 N hydrochloric acid (10 mL), followed by extraction with ethyl acetate (10 mL). The organic layer was washed successively with a saturated aqueous solution of sodium hydrogencarbonate (10 mL) and a saturated aqueous solution of sodium chloride (10 mL), and was then dried over anhydrous magnesium sulfate. The organic layer was concentrated under reduced pressure to afford the title compound (66 mg, 49%) as white crystals.
