There is disclosed a process for the preparation of an indanylamine compound of general formula
wherein R¹ represents an optionally substituted alkyl group, and R², R³ and R⁴ independently represent a hydrogen atom or an optionally substituted alkyl group, the process including the steps of hydrogenating a compound of general formula
wherein R¹, R², R³ and R⁴ are as described above and R⁵ and R⁶ independently represent a halogen atom, a hydroxyl, nitro or cyano group, or an optionally substituted alkyl, alkoxy, alkoxycarbonyl, alkylcarboxy or alkylamino group provided that R⁵ and R⁶ represent different atoms or groups, and subsequent rearrangement and derivatisation of the product thereof. Compounds of general formula I may be used to prepare preferred stereoisomers of fungicidal N-indanyl carboxamide compounds.
