3920-50-1<\/a>, Adding some certain compound to certain chemical reactions, such as: 3920-50-1, name is Pyrazole-3-carboxaldehyde, 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 3920-50-1.<\/p>\n

Reference Example 11-1 1 1-Allyl-1H-pyrazole-5-carbaldehyde Pyrazole-3-carbaldehyde (3.00 g, 31.2 mmol) was dissolved in DMF (20 ml), and thereto were added potassium carbonate (6.47 g, 46.8 mmol) and allyl bromide (3.50 g, 32.8 mmol) with stirring. The mixture was stirred at room temperature for 6 hours, and thereto was added water, and the mixture was extracted with ethyl acetate. The organic layer was washed with water and saturated saline, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and the resulting residue was purified by silica gel column chromatography to give the title compound (429 mg, 10 percent). 1H NMR (CDCl3, 400 MHz) delta 9.86 (s, 1H), 7.59 (d, 1H, J = 2.0 Hz), 6.93 (d, 1H, J = 2.0 Hz), 6.04 – 5.94 (ddt, 1H, J = 10.3, 17.1, 5.7 Hz), 5.19 (dd, 1H, J = 1.2, 10.3 Hz), 5.16 (d, 2H, J = 5.7 Hz), 5.09 (dd, 1H, J = 1.2, 17.1Hz).<\/p>\n
