Provided herein are novel processes for the preparation of phenylcyclopropylamine derivatives, which are useful intermediates in the preparation of triazolo[4,5-d]pyrimidine compounds. Provided particularly herein are novel, commercially viable and industrially advantageous processes for the preparation of a substantially pure ticagrelor intermediate, trans-(1R,2S)-2-(3,4-difluorophenyl)-cyclopropylamine. Provided further herein are novel acid addition salts of trans-(1R,2S)-2-(3,4-difluorophenyl)-cyclopropylamine, and process for their preparation. The intermediate and its acid addition salts are useful for preparing ticagrelor, or a pharmaceutically acceptable salt thereof, in high yield and purity.
