Participants

Reaction Steps

Sodium hydride (0.024 g, 0.990 mmol; 60% in oil) is added to a solution of (S)-4-(1H-Indol-5-yloxy)-6-methyl-5,8-dihydro-6H-pyrido[3,4-d]pyrimidine-7-carboxylic acid tert-butyl ester, Example 53-B-1, (0.126 g, 0.330 mmol) and DMF (7.5 mL) at it. After 5 min 3-(1-Methyl-cyclopropyl)-5-phenoxycarbonylamino-pyrazole-1-carboxylic acid tert-butyl ester, Example 5-D, (0.178 g, 0.495 mmol) is then added. After 1 h the mixture is quenched by the addition of saturated aqueous NH4Cl and then concentrated. The residue is separated directly via FCC (20-70% EtOAc/heptane). MS (ESI) m/z 644.2 (M+1).
