Adding a certain compound to certain chemical reactions, such as: 930-36-9, name is 1-Methylpyrazole, belongs to pyrazoles-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 930-36-9, SDS of cas: 930-36-9<\/a><\/p>\n

Phosphorus oxychloride (6.92 g, 45.1 mmol, 1.50 equiv.) was cooled to 0 0C and then added drop-wise to anhydrous DMF (3.50 mL, 45.2 mmol, 1.50 equiv.) at 0 0C. The mixture was stirred 1 hour at room temperature and was then heated to 80 0C. The compound of formula VIII (2.50 mL, 30.2 mmol) was then added drop-wise to the reaction, and the resulting mixture was stirred 3 hours at 95 0C. The reaction was then quenched by slow addition to ice (40 g). The pH of the resulting solution was 2, and it was raised to 5 by slow addition of 12N aqueous sodium hydroxide solution (11.2 mL). The resulting aqueous solution was extracted with dichloromethane and\/or ether (7 x 40 mL), and additional sodium hydroxide was added during extraction, as needed, to maintain a pH of 5. The extracts were then combined, dried over sodium sulfate, filtered and concentrated to yield a brown oil (3.79 g, 59% yield).<\/p>\n
