    - crystallisation with another solvent / solvent mixture (higher content of water or i-PrOH/water)


    MW49-10:
    Start time: 10:30 PM 24/11/2010
    End time: 13:00 PM 24/11/2010

    Solvent: EtOH/water 9:1, 5 mL
    - at first no crystals, stirring -> precipitate
    - heated again - formation of crystals after 30 min
    - after 3 h: 155 mg (55%)
    m.p. = 136-138°-c
    - salt: [α]D20 = -103° (c = 1, DMSO)

    2. Crystallization: Solvent: EtOH/water 2:1, 3 mL
