Reaktionsschritte

A mixture of 6-chloro-pyrimidin-4-ylamine (194 mg, 1.5 mmol, 1.3 equiv), 4-(2-morpholin-4-yl-ethoxy)-phenylamine (256 mg, 1.15 mmol) in H2O (1 mL) and glacial acetic acid (5 mL) is stirred for 16 h at 100° C. After solvent evaporation, the residue is taken up in DCM and diluted with a saturated aqueous solution of NaHCO3. The aqueous layer is separated and extracted with DCM. The organic phase is washed with brine, dried (Na2SO4), filtered and concentrated. The residue is triturated in EtOAc to provide the title compound as a grey solid: ESI-MS: 316.2 [MH]+; tR=1.00 min (purity: 95%, system 1); TLC: Rf=0.22 (DCM/MeOH+1% NH3aq, 93:7).
