摘要: 5-(α-Chlorovinyl)-2,4-dichloropyrimidine (I) on treatment with sodium methoxide in methanol was converted to 2,4-dimethoxy-5-ethynylpyrimidine (II) which silylated by t-butyl lithium and chlorotrimethylsilane 2,4-dimethoxy-5-β-trimethylsilyl)ethynylpyrimidine (IV). Compound IV deblocking trimethylsilyl iodide yielded 5-(β-trimethylsilyl)ethynyluracil (V), hydroxide 5-ethynyluracil (VI).
