title: 3,3-Dieth-oxy-5-fluoro-2,3-dihydro-1H-indol-2-one.
abstract: The title ketal, C(12)H(14)FNO(3), crystallized with two independent molecules in the asymmetric unit. In each molecule the fused ring system is essentially planar [maximum deviations of 0.0169 (11) and 0.0402 (13) Å]. The mol-ecules are each hydrogen bonded across a center of inversion into a dimer; adjacent dimers are linked by another N-H⋯O hydrogen bond, forming a chain running along [100].
