合成路线1

该中间体在本合成路线中的序号：(I)

Condensation of 2-methyl-4-(3-methylbenzyl)-3-oxobutanoic acid methyl ester (I) with O-methyl isourea (II) led to the formation of 5-methyl-6-(3-methylbenzyl)-3,4-dihydro-2-methoxy-4-oxopyrimidine (III). Subsequent displacement of the methoxy group linked at C-2 of the pyrimidine ring by treatment with cyclohexoxy potassium salt furnished 2-cyclohexoxy-5-methyl-6-(3-methylphenyl)-3,4-dihydro-4-oxopyrimidine
