反応手順
As in Example 2, a melt of 10 g (0.0455 mol) of 3,5-diphenylpyrazole and 0.44 g (0.0045 mol) of methanesulfonic acid was introduced and reacted over the course of 4 hours with 175 g (5.46 mol) of gaseous methanol (vaporized at 160° C.). 10 g (92%) of 1-methyl-3,5-diphenylpyrazole were obtained, boiling point 190° C./3 mbar, with a content of 98% (GC).
