The synthesis of 2-amino-5-{[4-(4-amino-benzyl)-phenylamino]-methyl}-3,7-dihydro-pyrrolo[2,3-d]pyrimidin-4-one 24 follows the same steps as the synthesis of 4-[(2-amino-4-oxo-4,7-dihydro-3H-pyrrolo[2,3-d]pyrimidin-5-ylmethyl)-amino]-benzoic acid 21, except that octanoic acid{5-[(dibenzylamino)-methyl]-4-oxo-4,7-dihydro-3H-pyrrolo[2,3-d]pyrimidin-2-yl}-amide 18 is reacted with 4,4′-methylene dianiline 22 to form octanoic acid (5-{[4-(4-amino-benzyl)-phenylamino]-methyl}-4-oxo-4,7-dihydro-3H-pyrrolo[2,3-d]pyrimidin-2-yl)-amide 23. Octanoic acid (5-{[4-(4-amino-benzyl)-phenylamino]-methyl}-4-oxo-4,7-dihydro-3H-pyrrolo[2,3-d]pyrimidin-2-yl)-amide 23 is then reacted with 5M KOH to form 2-amino-5-{[4-(4-amino-benzyl)-phenylamino]-methyl}-3,7-dihydro-pyrrolo[2,3-d]pyrimidin-4-one 24.
