title: 3-Hydr-oxy-3-[(2-methyl-propano-yl)meth-yl]indolin-2-one.
abstract: The title compound, C(13)H(15)NO(3), was synthesized by the Aldol reaction of isatin and 3-methyl-butan-2-one refluxing in methanol catalyzed by dimethyl-amine. The packing of the mol-ecules in the crystal structure features inter-molecular N-H⋯O and O-H⋯O hydrogen bonds.
