Versuchsvorschrift

To a solution of ethyl 2,4-dichloropyrimidine-5-carboxylate (1.4) (600 mg, 2.714 mmol), in CH3CN (12 mL), was added DIEA (0.750 mL, 4.313 mmol, 1.589 equiv), followed by 4-(1H-1,2,4-triazol-1-yl)aniline (465 mg, 2.902 mmol, 1.07 equiv). The mixture was stirred at room temperature for 20 h, then diluted with water (6×) to precipitate ii. The solid product was collected by filtration, rinsed with water (100 mL), and air dried; Yield, 850 mg (91%).
