Copper(I)-catalyzed arylation of dialkyl cyanomethanephosphonate anions in hot hexamethylphosphoric triamide affords α-arylalkanenitriles in moderate to good yields.
Provided are processes for preparing Ticagrelor and its intermediates that are useful in the processes. Also provided are salts of Ticagrelor, their processes and solid dispersion of Ticagrelor having Ticagrelor in amorphous form.

The equilibrium conversion of nitriles in the reaction of cyanoalkylphosphonates with methanol in the presence of sodium methylate, as determined by potentiometric titration with perchloric acid in nitromethane, varies from 58 to 17.7%. The practical yields of imidates were evaluated by a preparative procedure of isolation of purified imidates from the reaction mixtures (56-14%). Because of the low conversions of nitriles, the reaction is expedient to use only for preparing alkyl (dialkoxyphosphoryl)acetimidates.
