Adding a certain compound to certain chemical reactions, such as: 2533-69-9, name is Methyl 2,2,2-trichloroacetimidate, belongs to chlorides-buliding-blocks 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 2533-69-9, Recommanded Product: Methyl 2,2,2-trichloroacetimidate
Step 4: Synthesis of methyl 1-{3-[(tert-butoxycarbonyl)amino]propyl}-2-(trichloromethyl)-1H-benzimidazole-6-carboxylate To a stirred solution of methyl 4-amino-3-({3-[(tert- butoxycarbonyl)amino]propyl}amino)benzoate (4.7 g, 14.5 mmol) in acetic acid (50 mL) is added methyl trichloroacetimidate (3.1 g, 17.4 mmol). After 3 h at room temperature, the solvent is evaporated, the residue is dissolved in EtOAc, and is washed with Na2C03 and brine. The organic layer is dried (Na2S04) and evaporated. The residue is triturated with hexanes to afford the title compound (5.2 g, 80%) as a fine powder. LCMS (Method T), 1.85 min, 450.63 (MH+).
At the same time, in my other blogs, there are other synthetic methods of this type of compound, Methyl 2,2,2-trichloroacetimidate, and friends who are interested can also refer to it.
