PROCEDURE
实验过程
All routes start with saponification of Pemetrexed IM8 in water at IT=20° C. to 30° C. using 3.25 eq of NaOH. Upon complete conversion an aqueous solution of Pemetrexed Disodium with a pH of 13.0 to 13.5 is obtained. Starting from this mixture the desired route can be accessed by addition of HCl to adjust the pH to a certain value (depending on the route, FIG. 20).
