Related Products of 15937-07-2,Some common heterocyclic compound, 15937-07-2, name is 5,6-Dimethoxyindoline, molecular formula is C10H13NO2, 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.
Step 4: To a solution of 2-(4-nitro-1 H-pyrazol-1 -yl)acetaldehyde (942 mg, 6.08 mmol) in DCM (60.0 mL), 5,6-dimethoxyindoline (from step 1 ) (1 .09 g, 6.08 mmol) and STAB (1.55 g, 7.29 mmol) was added. After stirring at rt fori h, the reaction mixture was quenched with water and extracted with DCM (2x). The combined org. layers were concentrated and purification was performed by FC (EtOAc/ hex 1 :4 to 1 :1 ) to yield 5,6-dimethoxy-1-(2-(4-nitro- 1 H-pyrazol-1 -yl)ethyl)indoline as a brown solid. LC-MS conditions B: tR = 0.65 min, [M+H]+= 319.19.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 5,6-Dimethoxyindoline, its application will become more common.
