To a solution of 4-(1H-Indol-5-yloxy)-5-methyl-5,7-dihydro-pyrrolo[3,4-d]pyrimidine-6-carboxylic acid tert-butyl ester (400 mg, 1.092 mmol) in THF (10 mL) at 0° C., sodium hydride (74.2 mg, 1.856 mmol, 60% in mineral oil) is added. After 10 min, 1-isocyanato-3-trifluoromethyl-benzene (0.314 ml, 2.183 mmol) is added and the reaction is allowed to reach rt. After 2 h, a saturated solution of NH4Cl in water (5 mL) is added. The organics are extracted with EtOAc (×3), dried and evaporated to give the crude 5-methyl-4-[1-(3-trifluoromethyl-phenylcarbamoyl)-1H-indol-5-yloxy]-5,7-dihydro-pyrrolo[3,4-d]pyrimidine-6-carboxylic acid tert-butyl ester. MS (ESI) m/z 554.9 (M+1)
