摘要:
The invention relates to a method for the preparation of escitalopram by cyanation of optically active intermediates of the formulas (III) and (II) below, and the preparation of such intermediates by optical resolution.
摘要:
Disclosed is a method for the preparation of citalopram comprising conversion of a compound of Formula VIII wherein Z is halogen, to a compound of Formula IV followed by conversion of the compound of Formula IV into citalopram. Methods for the preparation of the compound of Formula IV are also disclosed.
摘要:
A novel method is provided for the manufacture of escitalopram. The method comprises chromatographic separation of the enantiomers of citalopram or an intermediate in the production of citalopram using a chiral stationary phase such as Chiralpak™ AD or Chiralcel™ OD. Novel chiral intermediates for the synthesis of Escitalopram made by said method are also provided.
摘要:
The invention relates to a method for the preparation of citalopram comprising reaction of a compound of formula II with a compound having the formula wherein R is halogen or —O—SO2—X, wherein X is alkyl, alkenyl, alkynyl or optionally alkyl substituted aryl or aralkyl, and R1 is dimethylamino, halogen, —O—SO2—X wherein X is as defined above, provided that R is not halogen when R1 is dimethylamino; and if R1 is dimethylamino followed by isolation of citalopram base or a pharmaceutically acceptable acid addition salt thereof, and if R1 is halogen or —O—SO2—X, wherein X is as defined above, followed by conversion of the resulting compound of formula wherein R2 is halogen or a group of formula —O—SO2—X wherein X is as defined above to citalopram, followed by isolation of citalopram base or a pharmaceutically acceptable acid addition salt thereof.
摘要:
The present invention relates to a novel method for the preparation of diol intermediates having the formula (II) and/or the opposite enantiomer of an acylated diol having the formula (IV) useful for the preparation of escitalopram involving selective enzymatic acylation or deacylation.
摘要:
The present invention relates to a novel method for the preparation of diol intermediates having the formula (II) and/or the opposite enantiomer of an acylated diol having the formula (IV) useful for the preparation of escitalopram involving selective enzymatic acylation or deacylation.
摘要:
The present invention relates to Vitamin K-dependent protein compositions having a very low, or negligible, content of protein contaminants. The present invention also relates to method applicable in the preparation of such Vitamin K-dependent protein compositions. Such methods may either be used alone or in sequential combination with the purpose of reducing the relative content of protein contaminants. The present invention is particularly relevant in the preparation of compositions of coagulation factors selected from Factor X polypeptides (FX/FXa), Factor IX polypeptides (FIX/FIXa), Factor VII polypeptides (FVII/FVIIa), and the anticoagulant Protein C, in particular Factor VII polypeptides.
