Procedure
To a solution of 4-(4,6-dichloropyrimidin-2-yl)morpholine (prepared as described in Method 22; 932 mg, 4.0 mmol) and DMA (0.7 mL, 4.0 mmol) in ACN (40 mL), neat N1-phenyl-ethane-1,2-diamine (0.523 mL, 4.0 mmol) was slowly added. The reaction mixture was stirred at 70-80° C. under nitrogen. After 20 hours, the reaction mixture was cooled down, and the solvent was removed under reduced pressure. The crude product was partitioned between EtOAc (120 mL) and 0.1 M NaHCO3 (50 mL). The organic layer was washed with additional 0.1 M NaHCO3 (2×50 mL), brine (50 mL), dried, filtered and concentrated to give N1-(6-chloro-2-morpholinopyrimidin-4-yl)-N2-phenylethane-1,2-diamine, as an off-white solid (1.29 g, 96%). LC/MS (m/z): 334.0 (MH+), Rt 1.94 minutes.
