4-(3-Fluoro-4-methylanilino)-2-methylidene-4-oxobutanoic acid
The title compound, C12H12FNO3, crystallizes with two independent mol-ecules (A and B) in the asymmetric unit. The dihedral angle between the mean planes of the 3-fluoro-4-methyl-phenyl ring and the oxo-amine group is 25.7 (7)° in mol-ecule A and 71.3 (7)° in mol-ecule B, while the mean plane of the 2-methyl-idene-4-oxo-butanoic acid group is twisted by 76.2 (1)° from that of the oxo-amine grou...
