A highly efficient and general method for the synthesis of 5-(2-acylethynyl)-2,4-dimethoxypyrimidines starting from 2,4-dimethoxy-5-/2-(trimethylsilyl)ethynyl/pyrimidine is described. The 5-(2-acylethynyl)-2,4-dimechoxypyrimidines have been converted to 5-(2-acyl-1-iodovinyl) uracils and 5-(2-acylethynyl) uracils.
