Ion-exchange chromatography (IEX) is a frequently overlooked technique. This novel IEX method uses non-aqueous mobile phases to purify a non-crystalline intermediate after a reductive amination with D-xylose. IEX delivers a step change in strength and purity of the intermediate allowing successful downstream processing.
