Procedure

A mixture of 2-amino-5-morpholin-4-yl-benzamide (820.0 mg, 3.71 mmol, Heterocyclic Comm. 2001, 7, 473-480), 2,4,5-trichloropyrimidine (679.8 mg, 3.71 mmol) and potassium carbonate (614.6 mg, 4.45 mol) in THF (10 mL) was stirred at 50° C. for 20 h and at RT for 6 days. The reaction was diluted with water (10 mL) and extracted into EtOAc. The organic layer was washed with NaHCO3, brine and dried by passing through a funnel filled with MgSO4. The filtrate was evaporated and the residue triturated with ether (5×3 mL) to afford 2-(2,5-dichloro-pyrimidin-4-ylamino)-5-morpholin-4-yl-benzamide as a yellow solid (0.75 g) that was used without further purification in the subsequent step.
