実験手順

The title compound is synthesized according to general procedure GP2 starting from 1.5 g (5.7 mmol) 4-chloro-5-iodo-6-methyl-pyrimidin-2-ylamine (GP3) and 986 mg (8.4 mmol) 3-ethynyl-phenol using 106 mg (0.56 mmol) CuI, 390 mg (0.56 mmol) PdCl2(PPh3)2 and 8 mL (55 mmol) triethylamine in 12 mL dry DMF. For the work-up the solvent is removed in vacuo and the product is purified by chromatography on silica gel (DCM/MeOH gradient) and subsequently RP-HPLC (ACN/H2O gradient). Yield: 419 mg (29%).
