摘要: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.

权利人:US ARMY
摘要:A cw CO2 tunable laser is employed to irradiate an allyl halide selected from allyl chloride, allyl bromide, allyl fluoride, 2-methyl-3-chloropropene, and 2,3-dichloropropene and contained in one or more reaction cells at a predetermined pressure. A predetermined power level from about 25 to 150 watts, an irradiating time from about 0.2 second to about 60 seconds, and a selected radiation line for example P(36), P(32), P(28), P(26), or P(22) (that is resonant with an absorption band of the selected allyl halide) are employed to achieve dissociation of the selected allyl halide and to achieve a laser-induced photochemical synthesis of benzene and substituted benzenes.
