Versuchsvorschrift

To a solution of 4-(1H-indol-5-yloxy)-5,7-dihydro-pyrrolo[3,4-d]pyrimidine-6-carboxylic acid tert-butyl ester (3.59 g, 10.2 mmol) in THF (100 mL) at 0° C., NaH (0.611 g, 15.3 mmol) is added. After 10 min, 1-isocyanato-3-trifluoromethyl-benzene (2.93 mL, 20.4 mmol) is added and the reaction is allowed to reach room temperature. After 2.5 h, a saturated solution of NH4Cl in water (50 mL) is added. The mixture is extracted with EtOAc (×3), and the combined organic extracts are dried and evaporated to give the crude 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 540.9 (M+1).
