Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 89570-82-1, name is 3-Chloro-2-hydrazinyl-5-(trifluoromethyl)pyridine. This compound has unique chemical properties. The synthetic route is as follows. Quality Control of 3-Chloro-2-hydrazinyl-5-(trifluoromethyl)pyridine
A CEM-designed 10-mL pressure-rated vial was charged with POCl3(2 mL), 3-chloro-2-hydrazinyl-5-(trifluoromethyl)pyridine (211 mg,1mmol), 4-methoxylbenzoic acid or analogous acid (1mmol). The mixture was irradiated in a CEM Discover Focused Synthesiser (150 W, 140C, 200 psi, 15min). The mixture was cooled to room temperature by passing compressed air through the microwave cavity for 2 min. It was poured into cold ice (40 mL) and the formed precipitate filtered. The crude solid was recrystallised from EtOH to give the title compound 2a and others. All the other compounds were synthesised according to the same procedure.
