Embodiment 1
[0098] N-(4-(2-(Methylcarbamoyl)pyridin-4-yloxy)phenyl)-4-p-chlorophenylpyridinamide
[0099] Step a4-chloropicolinate chloride (formula 2)
[0100] Put 10g (0.081mol) of 2-pyridinecarboxylic acid, 1.3g (0.013mol) of sodium bromide and 13mL of chlorobenzene in a 250mL three-necked flask, after heating up to 50°C, slowly add 24mL of thionyl chloride dropwise, and the dropwise addition is complete Continue stirring for 3 minutes, heat up to 85°C, and reflux for 20 hours. After the reaction was completed, the solvent and excess thionyl chloride were evaporated under reduced pressure, and 15 mL of toluene was added and stirred for 5 minutes. After the solvent was evaporated, a yellow oily liquid was obtained, namely 4-chloropicolidinyl chloride, and 50 mL of toluene was added, and the solution was directly used react in the next step.
[0101] Step b4-chloro-N-picoline carboxamide (formula 3)
[0102] Put 30mL of 33% methylamine aqueous solution into a 250mL round-bottomed flas...
