Route of Synthesis (ROS)
| Conditions | Yield |
| With N-ethyl-N,N-diisopropylamine In 1,4-dioxane at 70℃; for 2h; Experimental Procedure A mixture of 2,4,6-trimethylpyrimidine II(110 mmol, 20.0 g) and 3,5-dimethyl-4-hydroxybenzonitrile III (110mmol, 16.2 g) Was reacted with N, N-diisopropylethylamine (DIEA) (132 mmol, 17. Og) in 100 mL of 1,4-dioxane at 70 ° C for 2 h, When the reaction solution was cooled to about 10 ° C, A 200 mL aqueous solution was slowly added to the reaction solution and stirred for 30 min, filtered and dried in vacuo to give 29.8 g of intermediate IV in a yield of 92.5% | 92.5% |
| With N-ethyl-N,N-diisopropylamine In 1,4-dioxane at 70℃; for 2h; Experimental Procedure 4.1.4 4-((2,6-Dichloropyrimidin-4-yl)oxy)-3,5-dimethylbenzonitrile (7) 2,4,6-trichloropyrimidine (6, 11mmol, 2.0g), DIEPA (13mmol, 1.7g) and 4-hydroxy-3,5-dimethylbenzonitrile (11mmol, 1.6g) were dissolved in 10mL 1,4-dioxane and the mixed solution were heated at 70°C for 2h. After the reaction mixture was brought to room temperature, 50mL cold water was poured into the mixture and stirred for another 30min, filtrated. The wet cake was dried at 55-60°C under vacuum to give the intermediate 7 as white solid with a yield of 92%, mp: 207-209°C. 1H NMR (400MHz, DMSO-d6, ppm) δ: 7.76 (s, 2H, C3,C5-Ph-H), 7.64 (s, 1H, pyrimidine-H), 2.12 (s, 6H). ESI-MS: m/z 294.2 [M+1]+. C13H9Cl2N3O (293.01). | 92% |
| With N-ethyl-N,N-diisopropylamine In 1,4-dioxane at 70℃; for 2h; Experimental Procedure Weigh 2,4,6-trichloropyrimidine (2.0g, 10.9mmol), 4-hydroxy-3,5-dimethylbenzonitrile (1.6g, 10.9mmol) and N,-diisopropylethylamine (3.6ml, 21.8mmol) in 25mL of 1,4-dioxane solution, stirred at 70 °C for 2h. After the reaction was detected by TLC, after the reaction solution was cooled, 100 mL of water was slowly added thereto, stirring was continued for 30 min, filtration was performed, and the vacuum drying oven was used for drying. A white solid was obtained as the compound 4-((2,6-dichloropyrimidin-4-yl)oxy)-3,5-dimethylbenzonitrile (2) in a yield of 91.8%. | 91.8% |
