反応手順
As in Example 2, a melt consisting of 10 g (0.0455 mol) of 3,5-diphenylpyrazole and 0.057 g (0.00455 mol) of dimethyl sulfate was prepared at 200° C. Over the course of 5 hours, 435 g (13.6 mol) of methanol were vaporized at 155° C. and passed through the melt which was maintained at 200° C. 10.4 g (96.9%) of 1-methyl-3,5-diphenylpyrazole were obtained, boiling point 190° C./3 mbar, with a content of 99.2% (GC).
