Participants

Conditions

Temperature: 150 °C

Procedure

7-(2,5-dichloro-pyrimidin-4-yloxy)-2-methyl-2,3-dihydro-isoindol-1-one (0.10 g), benzyl 4-amino-2-chloro-5-methoxy-benzoate (0.28 g), Pd2dba3 (18 mg), X-Phos (37 mg) and Cs2CO3 are weighed into a microwave vial and argon flushing is carried out. Then toluene (1 mL) and NMP (50 μL) are added, argon flushing is carried out again and the mixture is stirred for 5 min at 150° C. in the microwave. For working up the mixture is diluted with ACN (20 mL) and combined with Isolute (Separtis GmbH). The solvent is eliminated in vacuo and then purified by preparative HPLC. (IC50=53 nmol)

Workup

custompurified by preparative HPLC
