Lithium Hydroxide → 3-Hydroxy-2-[(1-piperidinylcarbonyl)amino]propionic acid

Participants

Reaction Steps

200 mg (0.869 mmol) of methyl 3-hydroxy-2-[(1-piperidinylcarbonyl) amino]propionate was dissolved in 6 ml of a solvent mixture of methanol tetrahydrofuran (1:1). 1.04 ml (1.04 mmol) of 1 N aqueous lithium hydroxide solution was added to the obtained solution, and they were stirred at room temperature for 30 minutes. The reaction mixture was concentrated under reduced pressure, and the concentrate was acidified with 1 N aqueous hydrochloric acid solution. After extracting with ethyl acetate, the organic layer was dried over anhydrous magnesium sulfate and then concentrated under reduced pressure to obtain the title compound.
