Syntesis and crystallographic structure studies of N-[5-methylisoxazole amino-3-yl]-3,5-di-tert-butylsalicylaldimine

Abstract

N-[5-Methylisoxazole amino-3-yl]-3,5-di-tert-butylsalicylaldimine [C19H26N2O2] was synthesized by the reaction of 3,5- di-tert-butylhydroxybenzaldehyde in absolute ethanol and 3-amino-5-methylisoxale in ethanole. Its structure was determined by X-ray crystallography. It crystallized in the monoclinic system, space group P21/n, with lattice parameters a=9.024(2)Å, b=22.592(10)Å, c=9.782(3)Å, β=116.548(2)°, Z=4, μ=0.601 mm-1, s=1.013, R=0.054 and wR=0.110 for 2949 observed reflections. The structures were solved by direct methods using the SHELX-97 program and refined on F2. The compound has four intramoleculer and three intermolecular contacts. 2007 © The Japan Society for Analytical Chemistry.
