Patent ID: 8461388

Claim:
A process for preparing N-propargyl 1-indanamine or its enantiomer, which comprises: (a) reacting racemic 1-aminoindan or its enantiomer with an allyhalide in presence of a base to give N-allyl-1-aminoindan or its enantiomer; (b) halogenating the N-allyl-1-aminoindan or its enantiomer with a halogenating agent in a suitable organic solvent to give N-(2,3 dihalo propyl)-1-aminoindan or its enantiomer; and (c) treating the N-(2,3-dihalo propyl)-1-aminoindan or its enantiomer with a suitable base to give N-propargyl 1-indanamine or its enantiomer.
