Synthese von 4‐Hydroxy‐dihydrogalegin und verwandten Guanidinderivaten

Abstract: Bd. 671 sation (bei vorsichtigem kherzusatz stets olige Abscheidung) wurden 18 mg Nadeln vom Schmp. 160 -164" erhalten. Nach nochmaligem Umkristallisieren aus k h a n 0 1 feine Nadeln vom Schmp. 168-170"; RF = 0.45; 0.54; 0.65 (Entwicklungsgemische A bzw. B bzw. C ; Pikrat: GroBe, gelbe Nadeln vom Schmp. 123-124". Pikrolorzat: Nach zwei Umkristallisationen aus vie1 siedendem Wasser bei sehr langsamer Abkiihlung mikrokristalline, gelbe Masse vom Schmp. 257-260" (Umlagerung in feine Nadeln ab 238"). Misch-Schmp.… Show more
