Reaction Steps

(S)-isopropyl 2-aminopropanoate hydrochloride (Oakwood, 500 mg, 2.98 mmol) and phenyl phosphorodichloridate (Aldrich, 662 mg, 2.98 mmol) was suspended in anhydrous DCM (25 mL). The reaction was cooled to −78° C. Triethylamine (604 mg, 830 μl, 5.97 mmol) was added dropwise. The reaction mixture was stirred at −78° C. for 1 h, then allowed to warmed up to room temperature and stirred for overnight. The solvent was removed, the residue was washed with dry ether. The filtrate was concentrated to give crude (2S)-isopropyl 2-(chloro(phenoxy)phosphorylamino)propanoate as a light yellow oil (0.8 g, 88%) and used without further purification.
