Procedure

4-(1H-Indol-5-yloxy)-5,8-dihydro-6H-pyrido[3,4-d]pyrimidine-7-carboxylic acid tert-butyl ester, Example 31-F (140 mg, 0.38 mmol) is dissolved in THF (5 mL) and NaH (31 mg, 0.76 mmol, 60% in mineral oil) is added followed by (3-cyano-5-trifluoromethyl-phenyl)-carbamic acid phenyl ester (428 mg, 1.15 mmol). After 24 h, the reaction is concentrated and then partitioned between DCM and water. The crude residue is purified via FCC (5-90% EtOAc/heptane) to give the title compound. MS (ESI) m/z 579.2 (M+1).
