Abstract
5 - Ethynyl - 4 - methyl - 2 - sulfomethyl - pyrimidine was synthesized using acetyl-ization method and its structure was charateristized by using FT - IR, HNMR and elment analysis. The reaction mechnism was discussed and the synthetic technique of 5 - (1 - chlorovinyl) - 4 - methyl - 2 - sulfomethyl - pyrimidine was improved to attain 71 % yield. 5 - Ethynyl - 4 - methyl - 2 - sulfomethyl- pyrimidine was prepared using potassium tert - butoxide as catalyst to obtain 68% yield at room temperature.
