Abstract
NEW MATERIAL:2,6-Dinitro-β-dimethylaminostyrene of formula I.
USE: Intermediate for the synthesis of 4-substituted indoles useful as a synthetic raw material of pharmaceuticals and pesticides. For example, the titled compound can be converted to 4-aminoindole and then to 4-hydroxyindole which is useful as a synthetic raw material of pindolol [1-(indol-4-yloxy)-3-(isopropylamino)-2-propanol] useful as an antiarrhythmic agent and hypotensive agent.
PROCESS: The compound of formula I is prepared by reacting 2,6-dinitrotoluene of formula II with N,N-dimethylformamide dimethyl acetal (DMF-DMA) for 5W15hr under heating and refluxing. The amount of the DMF-DMA is excess to that of the compound of formula II used as a raw material.
