Adding some certain compound to certain chemical reactions, such as: 69843-13-6, name is 1-Methyl-1H-pyrazol-4-amine, 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 69843-13-6. 69843-13-6
To a solution of 1-methyl-1H-pyrazol-4-amine (500 mg, 5 mmol, 1.0 eq) in dioxane (10 mL) was added cyanamide (273 g, 6.5 mmol, 1.3 eq) and conc. HCl (1 mL). The reaction was stirred at 100 oC for 12 h. The solvent was removed under reduced pressure. The residue was recrystallized from the co-solvent of MeOH and Et2O. 1-(1-methyl-1H-pyrazol-4-yl)guanidine hydrochloride (600 mg, yield: 55%) was obtained as a yellow solid. ESI-MS (M+H)+: 140.1. 1H NMR (400 MHz, CD3OD) delta: 7.78 (s, 1H), 7.48 (s, 1H), 3.91 (s, 3H).
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 1-Methyl-1H-pyrazol-4-amine.
