  • Processes and intermediates useful to make antifolates
    Patent number: 6090168
    Abstract: The present application relates to a series of novel sulfonic acid metal cation salts of the formula ##STR1## which are useful intermediates to prepare antifolate 5-substituted pyrrolo[2,3-d]pyrimidines. The present invention also relates to a novel process for preparing the sulfonic acid metal cation salts and to a novel process for preparing aldehydes of the formula ##STR2## from the corresponding sulfonic acid metal cation salts.
