Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 1369959-12-5, name is 3-Chloro-5-nitro-1H-pyrazole, A new synthetic method of this compound is introduced below., name: 3-Chloro-5-nitro-1H-pyrazole<\/a><\/p>\n

Aqueous HCI (16.8 mL, 544 mmol) was added over a period of 10 min to a solution of compound 1-1 b (4.0 g, 27.1 mmol) in MeOH (200 mL). The reaction mixture was cooled to 0 C and tin(ll) chloride (30.0 g, 158 mmol) was added portion wise and the resulting reaction mixture was stirred at rt. The progress of the reaction was monitored by TLC and after 16 h, when starting material was deemed consumed, the solvent was evaporated. The residue was diluted with EtOAc (100 mL) and 30% aqueous NaOH solution (120 mL) was added dropwise at 0 C until basic pH, then stirred at 0 C for 2h. Solid precipitates were filtered off through a pad of Celite and the cake was rinsed with EtOAc (50 mL) and water (50 mL). The organic phase was separated and the aqueous phase was extracted with EtOAc (50 mL). The combined organic layers were washed with brine (50 mL), dried (Na2S04), filtered and concentrated under vacuum which gave the title compound (3.5 g, 93 %). The compound was used in next step without further purification. MS (ES+) 1 18.04 [M+H]+.<\/p>\n
