Procedure

EP436492 discloses process for preparation of R-(+)-Rasagiline hydrochloride which involves reaction of racemic 1-aminoindan (2) with propargyl chloride (6) in presence of potassium carbonate in acetonitrile (ACN) at 60° C. for 16 hours to obtain racemic Rasagiline base (4) which is purified using column chromatography. The ethereal solution of purified racemic base is then treated with HCl gas followed by recrystallization using isopropanol (IPA) to obtain racemic Rasagiline hydrochloride (7). R-(+)-Rasagiline is separated from the obtained racemic Rasagiline base (4) by preparative HPLC chromatography and further converted to its hydrochloride salt.
