ethyl 2-(cyclohexylamino)acetate

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

実験手順: To a solution of cyclohexylamine (45 g, 0.45 mol) in dichloromethane (100 mL) was slowly added bromo-acetic acid ethyl ester (15 g, 0.09 mol) in dichloromethane (150 mL) at 0° C. After the addition, the mixture was stirred at room temperature for 1 h and then washed with water (3×200 mL). The organic solution was dried with Na2SO4 and concentrated in vacuo. The residue was purified with chromatography (DCM: MeOH=30:1) to give cyclohexylamino-acetic acid ethyl ester as an oil. MS: 186 (M+H)+. at 0° C After the addition washed with water (3×200 mL) The organic solution was dried with Na2SO4 concentrated in vacuo The residue was purified with chromatography (DCM: MeOH=30:1)
