Procedure

[3-(2-Diethylamino-ethoxy)-4-methoxy-phenyl]-[5-(4-methoxy-phenyl)-pyrimidin-2-yl]-amine can be synthesized by the following procedure. To a solution of 2-methoxy-5-[5-(4-methoxy-phenyl)-pyrimidin-2-ylamino]-phenol (0.2 mmol) (from Example 5v) in anhydrous DMF (2 mL) is added Cs2CO3 (0.28 mmol) and (2-chloro-ethyl)-diethyl-amine (0.2 mmol). The reaction mixture stirred at 80° C. for 8 h and quenched with water followed by extraction with DCM (3×30 mL). The organic layer is washed with brine, dried over Na2SO4 and concentrated. Preparative LCMS purification affords the title compound (78%). MS (m/z) (M+1)+ 423.1.
