2-chloro-N-(1-hydroxybutan-2-yl)acetamide

反応条件: temp:0.00; pressure:0.00; stir:

反応条件: temp:-70.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a mixture of 2-amino-1-butanol (5.0 mL, 53 mmol) and triethyl amine (15.0 mL, 111 mmol) in dichloromethane (20 mL) at −70° C. was added chloroacetyl chloride (4.6 mL, 58 mmol) dropwise. The reaction mixture was stirred at −70° C. for 15 min. and then was allowed to warm to rt. It was diluted with EtOAc (50 mL) and the reaction was quenched by adding water (50 mL). The organic layer was separated and the aqueous layer was extracted with EtOAc (3×30 mL). The combined organic layers was concentrated to afford 2-(2-chloroacetamido)-1-butanol (8.6 g, 98%) as a brown solid. to warm to rt the reaction was quenched by adding water (50 mL) The organic layer was separated the aqueous layer was extracted with EtOAc (3×30 mL) The combined organic layers was concentrated
