甲基 2-(氨基甲基)-2-乙基丁酸酯

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Methyl2-(aminomethyl)-2-ethyl-butanoate (Intermediate 201; 8 g, 50 mmol) and acetone (4.35 g, 75 mmol) were added to methanol (230 mL) and stirred for 10 minutes before the rapid addition of sodium triacetoxyborohydride (15.9 g, 75 mmol). The reaction was stirred overnight before being evaporated to dryness. The residue was quenched with saturated K2CO3(aq) (100 mL), extracted with DCM (3×150 mL), dried and solvent evaporated to yield a dark liquids. Purification was achieved via distillation (65 oC @ 0.18 mbar) to yield the title compound as clear oil (5.3 g, 53%) before being evaporated to dryness The residue was quenched with saturated K2CO3(aq) (100 mL) extracted with DCM (3×150 mL) dried solvent evaporated to yield a dark liquids Purification was achieved via distillation (65 oC @ 0.18 mbar)
