Adding a certain compound to certain chemical reactions, such as: 62002-31-7, 4,5,6,7-Tetrahydro-3H-imidazo[4,5-c]pyridine dihydrochloride, 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, Safety of 4,5,6,7-Tetrahydro-3H-imidazo[4,5-c]pyridine dihydrochloride, blongs to pyridine-derivatives compound. Safety of 4,5,6,7-Tetrahydro-3H-imidazo[4,5-c]pyridine dihydrochloride
At 0 C., EDC (0.45 g, 2.4 mmol) was added to a solution of 1-hydroxy-7-azabenzotriazole (0.32 g, 2.4 mmol) and 2-norbornaneacetic acid (0.338 mL, 2.4 mmol) in dichloromethane (30 mL). The reaction mixture was stirred for 20 min at 0 C. 4,5,6,7-Tetrahydroimidazo[4,5-c]pyridine dihycrochloride (0.50 g, 2.3 mmol) was added. Ethyldiisopropylamine (0.40 mL, 2.3 mmol) was added. The reaction mixture was stirred for 16 h at room temperature. It was diluted with ethyl acetate (100 mL) and washed with a saturated aqueous solution of sodium hydrogencarbonate (100 mL). The aqueous solution was extracted with ethyl acetate (2*60 mL). The combined organic layers were dried over magnesium sulfate. The solvent was removed in vacuo. The crude product was purified by flash chromatography on silica (40 g), using dichloromethane/methanol/25% aqueous ammonia (100:10:1) as eluent, to give 120 mg of the title compound. 1H NMR (CDCl3, 2 rotamers): delta 1.00-2.50 (m, 13H); 2.65 and 2.75 (both t, together 2H); 3.75 and 3.90 (both t, together 2H); 4.55 and 4.65 (both s, together 2H); 7.53 (s, 1H).
At the same time, in my other blogs, there are other synthetic methods of this type of compound,62002-31-7, 4,5,6,7-Tetrahydro-3H-imidazo[4,5-c]pyridine dihydrochloride, and friends who are interested can also refer to it.
