5-[2-(METHYLTHIO)ETHOXY] AND PYRIMIDINE-2-AMINE MANUFACTURING METHOD

摘要

A novel method for preparing 5-[2-(methylthio)ethoxylpyrimidin-2-amine useful as a regent or raw material for manufacture of medicaments, agricultural chemicals, and industrial products, which comprises alkanoylating the amino group of a 2-amino-4-alkoxypyrimidine, then converting the resultant into a 4-hydroxypyrimidine compound by a treatment with anhydrous aluminum chloride, further etherifying the 4-hydroxypyrimidine compound by a reaction with a 2-haloethyl methyl sulfide in the presence of a base, and removing the alkanoyl group to obtain 5-[2-(methylthio)ethoxylpyrimidin-2-amine.
