Reaction Steps

tert-Butyl 2-(4-(oxazol-5-yl)phenylamino)-4-((tetrahydro-2H-pyran-4-yl)methylamino)-7,8-dihydropyrido[4,3-d]pyrimidine-6(5H)-carboxylate (330 mg, 0.65 mmol) was dissolved in methanol (3 mL). Hydrochloric acid (0.020 mL, 0.65 mmol) was added and the reaction mixture was stirred at 80° C. for 30 minutes. The solvent was evaporated and the crude was used as such in the subsequent step.
