该中间体在本合成路线中的序号：(V)The oxidation of 4,6-dichloro-2-(methylsulfanyl)pyrimidine (I) with MCPBA in dichloromethane gives 4,6-dichloro-2-(methylsulfonyl)pyrimidine (II), which is condensed with N-(4-sulfanylphenyl)cyclopropanecarboxamide (III) in hot butanol to yield the diaryl thioether (IV). The reaction of (IV) with 3-methyl-1H-pyrazol-5-amine (V) by means of DIEA in hot DMF affords the secondary amine (VI), which is finally condensed with 1-methylpiperazine (VII) by heating at 110 ºC to provide the target compound (1). Scheme 1.
