Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 13726-14-2, name is 4-Chloro-3-methoxyaniline, A new synthetic method of this compound is introduced below., category: chlorides-buliding-blocks
To a solution of 2-t-butoxycarbonylaminobenzoic acid (115 mg, 0.485 mmol) in DMF (2.0 mL) was added a solution of 4-chloro-3-methoxyaniline (82.2 mg, 0.522 mmol), HOBt (70.0 mg, 0.518 mmol), EDCI·HCl (104 mg, 0.542 mmol) and DIEA (90.0 muL, 0.522 mmol) in DMF (1.0 mL). The resulting mixture was stirred at r.t. overnight. After completion of the reaction, AcOEt was added. The organic layer was washed with water and brine, dried, and concentrated to give the title compound as a pale yellow paste, which was used for the next step without further purification.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
