合成路线1
The synthesis can be performed by two related ways: 1) The condensation of 2-(methylsulfanyl)pyrimidin-4-ol (I) with 4-aminobenzonitrile (II) in hot diglyme gives 4-(4-hydroxypyrimidin-2-ylamino)benzonitrile (III), which is treated with POCl3 to yield the corresponding chloro derivative (IV). Finally, this compound is condensed with 2,4,6-trimethylaniline (V) in dioxane to afford the target 4-aminobenzonitrile derivative. 2) Condensation of 2,4,6-trimethylaniline (VI) with 2,4-dichloropyrimidine (VII) by means of DIEA in refluxing 1,4-dioxane, followed by chromatographic purification furnishes intermediate (VIII), which is finally converted into the desired compound by condensation with 4-aminobenzonitrile (II) in refluxing water by means of HCl in 2-propanol.
