合成路线1
该中间体在本合成路线中的序号:(II)The condensation of 7-methylindan-4-ol (I) with crotyl chloride (II) by means of NaH in DMF gives 1-(7-methylindan-4-yloxy)-trans-2-butuene (III), which is epoxidized with H2O2 in MeCN-MeOH yielding 1-(7-methylindan-4-yloxy)-trans-2,3-epoxybutane (IV). Finally, this compound is treated with isopropylamine (A) in refluxing water.

合成路线2
该中间体在本合成路线中的序号:(IV)When 4-(3-methylphenyl-3-oxobutanoic acid methyl ester (I) were reacted with thiourea (II), in the presence of sodium methoxide, condensation occurred with formation of 3,4-dihydro-6-(3-methylbenzyl)-4-oxo-2-thioxopyrimidine (III). Reaction of the compound (III) with 1-chloro-but-2-ene (IV) in alkaline medium afforded the required 2-but-2-enylthio)-6-(3-methylbenzyl)-3,4-dihydro-4-oxopyrimidine
