Danegaptide Hydrochloride → (2S,4R)-1-(2-aminoacetyl)-4-benzamidopyrrolidine-2-carboxylic acid hydrochloride monohydrate

Participants

Reaction Steps

36.5 mg of amorphous (2S,4R)-1-(2-aminoacetyl)-4-benzamidopyrrolidine-2-carboxylic acid hydrochloride was dissolved in 0.5 mL of an acetone/water (19.5:0.5 ratio by volume) mixed solvent at room temperature. The container was stirred and the crystals that had formed were collected. The crystalline solid was dried at 40-50° C. under vacuum to give crystalline (2S,4R)-1-(2-aminoacetyl)-4-benzamidopyrrolidine-2-carboxylic acid hydrochloride monohydrate.
