摘要: The invention provides a high-yield process for the preparation of letrozole having a high purity, without the need for removal of the 4-[1-(1,3,4-triazolyl)methyl]benzonitrile impurity at the intermediate stage. The invention also provides a process for the synthesis of letrozole in which formation of the impurity 4-[1-(1,3,4-triazolyl)methyl]benzonitrile during the first stage is minimized. In the process, a 4-(halomethyl)benzonitrile is reacted with a salt of 1H-1,2,4-triazole, reducing the formation of the impurity. Preferably, the preparation is conducted as a one-pot process.

摘要: Demethylepipodophyllotoxin-.beta.-glucosides are prepared by allowing demethylepipodophyllotoxin to react with a 2,3-di-O-ester of a 1-O-trialkylsilyl-4,6-O-alkylidene-.beta.-D-glucose derivative in the presence of a Lewis acid. The 4,6-O-alkylidene group can be alkylidene, arylalkylidene, or heteroarylalkylidene and the 2,3-ester can be lower alkanoyl or haloacetyl. In a typical embodiment, demethylepipodophyllotoxin is allowed to react with 4,6-O-ethylidene-2,3-di-O-acetyl-1-O-trimethylsilyl-.beta.-D-glucose in the presence of boron trifluoride etherate to yield etoposide 2",3"-diacetate.
