Aluminium lithium hydride → (2R,3S)-2-cyclopropylaminomethyl-pyrrolidin-3-ol

Participants

Reaction Steps

A mixture of (2S,3S)-3-hydroxy-pyrrolidine-2-carboxylic acid cyclopropylamide (3.5 g, 20 mmol) and LAH (2.3 g, 3 eq.) in THF (50 mL) was heated to reflux for 2 hours. The cooled reaction was diluted with water (2.3 mL), a few drops of 10% NaOH, then water (2.3 mL). After stirring for 30 mins, the insolubles were filtered off, the filtrate was concentrated to give 0.8 g of (2R,3S)-2-cyclopropylaminomethyl-pyrrolidin-3-ol as a pale yellow oil. MS m/z 157 [M++1].
