Chloroacetyl chloride → HCID 51357134, 화합물

온도

0 °C

To (2R)-2-[(phenylmethyl)amino]-1-propanol (8.43 g, 51 mmol) in THF (50 mL) was added a solution of K2CO3 (21.15 g, 153 mmol) in water (50 mL). To the resulting mixture at 0° C. was added slowly via syringe chloroacetyl chloride (5.7 mL, 71.4 mmol) with vigorous stirring, and the reaction mixture was stirred for 1 hour at 0° C. A 50% aqueous NaOH solution was added to adjust the pH>13, and the resulting mixture was warmed up overnight to room temperature. The solution was extracted with CH2Cl2 (2×200 mL), and the organic layer was dried (Na2SO4), filtered and concentrated to afford the title compound (100% crude yield) as a colorless oil. LC-MS (ES) m/z=206 [M+H]+
