The title compound crystallizes in the orthorhombic space group Pca21 with the following unit-cell parameters: a = 18.4391(15)Å, b = 4.2710(2)Å, c = 32.2187(16)Å and V = 2537.3(3)Å3. The crystal data were solved with a final R = 0.062 using 2394 independent reflections. There are two molecules in the asymmetric unit. The title compound adopts the keto-amine tautomeric form. In the structure, there are N-H...O and C-H ···O intramolecular hydrogen bonds and C-H · · ·O intermolecular hydrogen bonds. 2008 © The Japan Society for Analytical Chemistry.eninfo:eu-repo/semantics/openAccessNote2410X237x23810.2116/analscix.24.x2372-s2.0-68949172743N/A
