The present invention relates to an improved process for the preparation of optically chiral amino compound. The present invention particularly relates to the improved process for the preparation of (S)-1-amino-2,3-dihydro-1H-indene-4-carbonitrile, an important intermediate for the synthesis of ozanimod. The present invention more particularly relates to preparation of (S)-1-amino-2,3-dihydro-1H-indene-4- carbonitrile using 4-cyano-1-indanone and α-methylbenzylamine derivatives as starting materials. The present invention specifically relates to preparation of (S)-1- amino-2,3-dihydro-1H-indene-4-carbonitrile comprising diastereoselective chiral amine synthesis by protection with chiral auxiliary -methyl benzylamine derivatives followed by reduction and debenzylation.
