  • Method for the synthesis of rasagiline
    Patent number: 8901352
    Abstract: We have developed a new method for the synthesis of Rasagiline (Formula 1) based on the alkylation of trifluoroacetyl protected aminoindan. This protection enabled us to carry out an alkylation of aminoindan with a high yield and purity under very mild conditions with a wide range of reaction conditions and reagent selection. Considering the ease, purity and high yields of introducing and removal of the trifluoroacetyl group, this approach is a highly practical and economical way for the synthesis of rasagiline or its pharmaceutically acceptable salts.
