Reaction Steps

Using the general procedure for synthesizing naphthyl (amino acid ester) phosphorochloridates and tosylate salt of (S)-neopentyl 2-aminopropanoate (1.0 g, 2.8 mmol), (S)-methyl 2-(6-(dichlorophosphoryloxy)naphthalen-2-yl)propanoate (990 mg, 2.8 mmol), TEA (0.8 mL, 5.6 mmol) and DCM (20 mL) were combined to give 1.13 g of desired (2S)-methyl 2-(6-(chloro((S)-1-(neopentyloxy)-1-oxopropan-2-ylamino)phosphoryloxy)naphthalen-2-yl)propanoate in 83% yield as a gummy syrup.
