Abstract

1306065 Substituted benzylidene-bis-(methacrylamide) IMPERIAL CHEMICAL INDUSTRIES Ltd 6 Feb 1970 [10 Feb 1969] 6989/69 Heading C2C [Also in Divisions C4 and D1] Amines of the formula (wherein ring A may contain further substituents) are prepared by condensing 1 mole of an optionally substituted nitrobenzaldehyde with 2 moles of methacrylamide in the presence of a strong acid and reducing the resulting nitro - benzylidene - bis - methacrylamide, e.g. by catalytic hydrogenation or with iron powder in ethanol and formic acid. In Example I, there is described the preparation of 3-aminobenzylidene-bis- (methacrylamide) -
