The first general palladium-catalyzed amination of aryl phosphates is described. The combination of MorDalPhos with [Pd(π-cinnamyl)Cl]2 enables the amination of electron-rich, electron-neutral, and electron-poor aryl phosphates with a board range of aromatic, aliphatic, and heterocyclic amines. Common functional groups such as ether, keto, ester, and nitrile show an excellent compatibility in this

The invention discloses a process for preparation of highly pure dialkyl pemetrexed by reacting a 2-(4-hydroxy-6-aminopyrrolo(2,3-d)pyrimidin-3-yl)ethylbenzoic acid with a glutamatic acid diester or its salt in presence of a safe, mild, inexpensive, non-oxidative and easy to handle reagent such as substituted triphenyl phosphate. The invention further discloses purification of dialkyl pemetrexed by crystallization or trituration and conversion of purified dialkyl pemetrexed to pemetrexed or its disodium salt.
