Continuously updated synthesis method about 6-Chloro-5-fluoroindolin-2-one

The synthetic route of 100487-74-9 has been constantly updated, and we look forward to future research findings.

Reference of 100487-74-9, A common heterocyclic compound, 100487-74-9, name is 6-Chloro-5-fluoroindolin-2-one, molecular formula is C8H5ClFNO, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.

General procedure: To the mixture of optionally substituted 6-chlorooxindole (5.0 mmol) and 3-chloro-2-fluorobenzaldehyde (2.4 g, 15 mmol) (Oakwood) in methanol (50 mL) was addedpiperidine (Aldrich) (1.7 g, 20 mmol) dropwise. The mixture was then heated at 50 Cfor 3 h. After cooled to 4 C, the mixture was filtered and resulting precipitate wascollected, washed with cold methanol, dried to give the desired product.

The synthetic route of 100487-74-9 has been constantly updated, and we look forward to future research findings.
