A new synthetic route of 60434-13-1

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. 60434-13-1, name is 5-Chloro-1-methylindoline-2,3-dione, A new synthetic method of this compound is introduced below., Quality Control of 5-Chloro-1-methylindoline-2,3-dione

General procedure: A solution of N-methylisatin (161 mg, 1.0 mmol), indole (129 mg, 1.1 mmol), and K2CO3 (69 mg, 0.5 mmol) in aqueous DMF (H2O/DMF, 2:1, 3.0 mL) was heated to 50 oC for 3 h. After aqueous extractive workup and column chromatographic purification process (n-hexane/EtOAc, 1:1), 1a was obtained as a white solid, 170 mg (61%).1,2 Other compounds were synthesized similarly, and compounds 1a1,2 and 1l3,7 are known compounds. Compound1a?1,4 was prepared according to the reported method.16 The spectroscopic data of unknown compounds 1b-d are as follows.

The synthetic route of 60434-13-1 has been constantly updated, and we look forward to future research findings.
