The mixtures of KAB119-1 and MNR6-1 were suspended in IPA and water (with heat gun heating). If relevant, the additional solvent was added. The vials were sealed and stored in the dark at rt over the weekend. [data]5303[/data] [b]03/02/14.[/b] No crystals formed. The mixtures were concentrated under reduced pressure. Second attempt: X. Vial 2 was dissolved in 1:1, water:IPA, v/v (4 mL) and allowed to stand at rt. The clear yellow mixture turned into a gel. Water (4 mL) was added. The mixture was sonicated until a heterogenous yellow suspension. Isopropanol was added slowly. Sealed vial. The clear yellow solution at rt overnight.
