Reaction Steps

2-Amino-3-phenyl-propionic acid methyl ester is dissolved in 25 mL of methylene chloride and the reaction charged with triethylamine (0.97 mL, 7 mmol) and 4-chlorobenzenesulfonylchloride at 0° C. The reaction is allowed to warm to room temperature (rt) and stirred overnight. The reaction is quenched with sodium bicarbonate, extracted with methylene chloride, dried over sodium sulfate, and concentrated in vacuo. The resultant solid is triturated with 20% ethylacetate/hexanes to provide the title compound. 13C NMR (100 MHz, CDCl3) 39.5, 52.8, 57.1, 127.5, 128.8, 128.9, 129.5, 129.6, 135.1, 138.4, 139.4, 171.5. MS 354.1 m/z (M+1).
