Benzylamine (0.061 mL, 0.55 mmol) was added to tert-butyl 2-(4-(oxazol-5-yl)phenylamino)-4-(trifluoromethylsulfonyloxy)-7,8-dihydropyrido[4,3-d]pyrimidine-6(5H)-carboxylate (0.3 g, 0.55 mmol, Example 3c) in dioxane (4 mL) and the reaction mixture was stirred over night at 25° C. The solvent was removed under reduced pressure and the reaction mixture was redissolved in DCM and washed with water. The organic layer was dried (MgSO4), filtered and concentrated to give tert-butyl 4-(benzylamino)-2-(4-(oxazol-5-yl)phenylamino)-7,8-dihydropyrido[4,3-d]pyrimidine-6(5H)-carboxylate (0.238 g, 86%). MS (ESI+)/(ESI−) m/z 499/497
