Reaction Steps

Analogously to Example (15b), a mixture of 49.6 g of 1-methyl-3-methylthio-5-(4-methoxyphenyl)-1H-1,2,4-triazole, 40 g of L-methionine and 380 ml of methanesulphonic acid is heated for 24 hours in a bath at 110°-120° and analogously worked up, yielding 5-(4-hydroxyphenyl)-1-methyl-3-methylthio-1H-1,2,4-triazole having a melting point of 216°-220° (from isopropanol).
