合成路线1

Condensation of 2-chloro-5-nitropyridine (I) with cis-2,6-dimethylmorpholine (II) by means of K2CO3 in DMF at 50 °C gives intermediate (III), which is hydrogenated with H2 over Pd/C in MeOH to yield amine (IV) . Coupling of amine (IV) with 3-bromo-4-methylbenzoic acid (V) using HATU and Et3N or DIEA in DMF affords the corresponding amide (VI), which is finally submitted to Suzuki coupling with 4-(trifluoromethoxy)phenyl boronic acid (VII) in the presence of Pd(PPh3)4 and Na2CO3 in toluene/EtOH/H2O , DME or DME/H2O at 135 °C.
Alternatively, Suzuki coupling of 3-bromo-4-methylbenzoic acid (V) with 4-(trifluoromethoxy)phenylboronic acid (VII) in the presence of Pd(PPh3)4 and Na2CO3 in DME/H2O gives intermediate (IX), which is finally coupled with amine (IV) using HATU and Et3N in DMF .
