Reaction Steps

A solution of 4-(1H-indol-5-yloxy)-6-methyl-5,8-dihydro-6H-pyrido[3,4-d]pyrimidine-7-carboxylic acid tert-butyl ester (210 mg, 0.55 mmol), CDI (179 mg, 1.10 mmol), TEA (230 uL, 1.65 mmol), and DMF (5 mL) is stirred at rt 1 h before 5-tert-butyl-2H-pyrazol-3-ylamine (77 mg, 0.55 mmol) and 4-pyrrolidinopyridine (16.4 mg, 0.11 mmol) are added. After 24 h, the reaction is concentrated in vacuo and the purified via FCC (5-90% EtOAc/heptane) to give the title compound. MS (ESI) m/z 546.3 (M+1).
