Procedure

A homogeneous solution of 0.175 of diethyl N-(4-[2-(2-acetamido-4-hydroxypyrido[2,3-d]pyrimidin-6-yl)ethyl]benzoyl)-L-glutamate in 50 mL of methanol containing 3 mL of 1N aqueous sodium hydroxide was stirred at room temperature for 72 hours. Addition of 2 mL of acetic acid followed by centrifugation gave 0.125 g (86) of the title compound, which can be alternatively named as 5,10-dideazafolic acid, as a microcrystalline colorless solid, mp >200° C.; NMR (TFA-d1) delta 2.3-2.7 (m, 2H), 2.7-3.0 (m, 2H), 3.25 (s, 5H), 4.9-5.25 (m, 1H), 7.35, 7.85 (AB q, 4H, J=9 Hz), 8.50 (s, 1H), 8.90 (s, 1H).
