This invention relates to a process for synthesizing certain folic acid analogues, which are useful in treating cancer, inflammatory diseases, autoimmune diseases, and are commonly referred to as antifolates. The process employs improved steps for annulation, derivatization and addition reactions to produce the described antifolates from commonly available starting materials.
