반응 단계
As in Example 2, a melt of 10 g (0.0455 mol) of 3,5-diphenylpyrazole and 0.051 g (0.000455 mol) of methyl sulfate was introduced and reacted over the course of 3 hours with 197.75 g (6.18 mol) of gaseous (vaporized at 160° C.) methanol. 9.7 g (86.7%) of 1-methyl-3,5-diphenylpyrazole were obtained, boiling point 190° C./3 mbar, with a content of 95.2% (GC).
