Adding a certain compound to certain chemical reactions, such as: 59340-27-1, name is 1,3,5-Trimethyl-1H-pyrazole-4-sulfonyl chloride, 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 59340-27-1, Application In Synthesis of 1,3,5-Trimethyl-1H-pyrazole-4-sulfonyl chloride
Example 1 4-(3,4-Dichlorophenoxy)-1-((1,3,5-trimethyl-1H-pyrazol-4-yl)sulfonyl)piperidine 4-(3,4-Dichlorophenoxy)piperidine hydrochloride (143 mg, 0.508 mmol) (prepared as described for 4-(4-chloro-3-fluorophenoxy)piperidine hydrochloride (Intermediate 10) using 3,4-dichlorophenol) and triethylamine (142 muL, 1.16 mmol) in dichloromethane (10 mL) was treated with 1,3,5-trimethyl-1H-pyrazole-4-sulfonyl chloride (106 mg, 0.508 mmol). The reaction was stirred for 2 hours at room temperature. The crude reaction was washed with 1N hydrochloric acid, filtered through a phase separation cartridge and concentrated in vacuo. The crude product was purified by silica column chromatography eluting with petrol/ethyl acetate to give the title compound.
