Process for the production of a pemetrexed salt |
| abstract |
A process of making a pemetrexed salt comprising:n a) reacting a compound of formula II nn n n n n n n n n n or an acid salt thereof, wherein each of R 1 and R 2 is independently a C1-C6 alkyl group, with an aqueous basic solution at a temperature of no more than 10° C. to obtain a first mixture comprising the pemetrexed salt;n b) isolating the pemetrexed salt from the first mixture. |
