2-chloro-N-[(1R)-2-hydroxy-1-phenylethyl]propanamide

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a solution of 2-chloro-N-[(1R)-2-hydroxy-1-phenylethyl]propanamide from Step A (1.30 g, 5.71 mmol) in THF (100 mL) at 0° C. was added NaH (493 mg of a 60% dispersion in oil, 12.3 mmol) and the mixture was stirred at ambient temperature for 18 h. Saturated aqueous NaHCO3 (10 mL) was added and the mixture was extracted with EtOAc (3×20 mL). The combined organic layers were dried over Na2SO4, filtered, and concentrated in vacuo. The crude product was purified by silica gel chromatography, eluting with a gradient of hexane:EtOAc—75:25 to 0:100, to give the title compound. MS: m/z=192 (M+1). the mixture was extracted with EtOAc (3×20 mL) The combined organic layers were dried over Na2SO4 filtered concentrated in vacuo The crude product was purified by silica gel chromatography eluting with a gradient of hexane

実験手順: To a solution of (R)-2-phenylglycinol (1.00 g, 7.3 mmol) and triethylamine (1.02 mL, 7.3 mmol) in CH2Cl2 (50 mL) at 0° C. was slowly added 2-chloropropionyl chloride (0.72 mL, 7.3 mmol). After 20 min, the reaction mixture was quenched with saturated aqueous NaHCO3 (20 mL) and extracted with CH2Cl2 (2×50 mL). The combined organic extracts were washed with 10% citric acid, then brine, then dried over Na2SO4, filtered, and concentrated in vacuo to give the title compound. MS: m/z=228 (M+1). at 0° C. the reaction mixture was quenched with saturated aqueous NaHCO3 (20 mL) extracted with CH2Cl2 (2×50 mL) The combined organic extracts were washed with 10% citric acid brine, then dried over Na2SO4 filtered concentrated in vacuo
