How is (2S)-2-(Methylammonio)pentanoate (CAS: 19653-78-2) typically synthesized?

(2S)-2-(Methylammonio)pentanoate can be synthesized through the reaction of pentanoic acid with methylamine under basic conditions. Commonly, this is achieved via a condensation reaction in the presence of a catalyst like sodium hydroxide. The yield is typically high, and the product can be purified by recrystallization or other standard organic purification techniques.
