合成路线1
The condensation of 2-(2,6-difluorophenyl)acetic acid (I) with lmalonic acid monoethyl ester sodium salt (II) gives 4-(2,6-difluorophenyl)-3-oxobutyric acid ethyl ester (III), which is cyclized with thiourea (IV) to yield 6-(2,6-difluorobenzyl)-2-thioxo-1,2,3,4-tetrahydropyrimidin-4-one (V). Finally this compound is reacted with 1-ethylpropyl chloride (VI) by means of K2CO3 to afford the target pyrimidinone.
