Abstract:
A process for preparation of 4-aminoindane derivatives of a first formula, salts and enantiomers thereof comprising the steps of: a) hydrogenating a 1,2-dihydroquinoline of a second formula to give a corresponding tetrahydroquinoline of a third formula; b) acylating the tetrahydroquinoline of the third formula with a carboxylic acid derivative of a fourth formula to obtain a corresponding acyl derivative compound of a fifth formula; c) rearranging the acyl derivative compound of the fifth formula under acidic conditions so as to give an acyl indane compound of a sixth formula; and d) hydrolysing the acyl group of the acyl indane compound of the sixth formula so as to obtain the 4-aminoindane derivatives of the first formula.

Claim (Index 15):
The process of  claim 1 , wherein the step (c) comprises suspending the acyl derivative compound of Formula (VI) in an organic solvent and contacting the thus obtained suspension with sulphuric acid or orthophosphoric acid so as to obtain the acyl indane compound of Formula (VII) in a form of an addition salt.
