Reaction Steps

The reaction of N2-(3-ethoxycarbonylmethyleneaminophenyl)-N4-(3,4-ethylenedioxyphenyl)-5-fluoro-2,4-pyrimidinediamine (0.1 g) and LiOH (10 equivalents) in MeOH:water (1:1, v/v) for 1 h at room temperature followed by treatment with aqueous HCl gave the solid. The resulting solid was filtered, washed with water and dried to give N2-(3-carboxymethyleneaminophenyl)-N4-(3,4-ethylenedioxyphenyl)-5-fluoro-2,4-pyrimidinediamine. LCMS: ret. time: 18.23 min.; purity: 87.6%; MS (m/e): 412.01 (MH+).
