반응 단계
As in Example 2, a melt of 10 g (0.0455 mol) of 3,5-diphenylpyrazole and 0.72 g (0.00455 mol) of benzenesulfonic acid was introduced and reacted over the course of 4.5 hours with 245 g (7.66 mol) of gaseous methanol (vaporized at 160° C.). 9.6 g (88.5%) of 1-methyl-3,5-diphenylpyrazole were obtained, boiling point 190° C./3 mbar, with a content of 98.2% (GC).
