标题:Alpha-substituted pyrimidine-thioalkyl and alkylester compounds as inhibitors of viral reverse transcriptase
作者:Nugent, R.A.; et al. (Pharmacia & Upjohn AB)
来源:EP 0824524; WO 9635678
合成路线图解说明:

Alkylation of 4,6-dihydroxy-2-mercaptopyrimidine (I) with 4-methoxybenzyl chloride (II) provided methoxybenzyl sulfide (III). This was treated with POCl3 and 2-picoline to give dichloropyrimidine (IV). Then, ammonolysis with NH4OH in acetonitrile produced aminopyrimidine (V). Removal of the methoxybenzyl protecting group orf (V) was accomplished by treatment with methanesulfonic acid in CH2Cl2 to provide (VI). 4-Chlorocrotonyl chloride (VII) was condensed with diethylamine to yield chloro amide (VIII) (1). The title compound was then obtained by alkylation of mercaptopyrimidine (VI) with chloro amide (VIII) in the presence of NaOH in aqueous ethanol.
