Synthesis and X-ray diffraction crystallographic characterization of compound 2-(α-naphtyl)-3-(α-pyridinyl)-1,3-thiazolidin-4-one

Thiazolidinones present a wide range of useful applications especially in the biological aspect. Based on these facts, the compound of interest 2-(α-naphthyl)-3-(α-pyridinyl)-1,3-thiazolidine-4-one (C18H14N2OS), was synthesized via multi-component reaction with the aim of obtaining a compound that would show activity against fungi and bacteria. The synthesis of 2-(α-naphthyl)-3-(α-pyridinyl)-1,3-thiazolidine-4-one, was carried out from the respective α-aminopyridine with α-naphthylaldehyde and α-mercaptoacetic acid, under reflux in dry toluene for 8 h, obtaining a solid compound. Molecular characterization of the compound was carried out by infrared spectrometry, mass spectrometry, and nuclear magnetic resonance. The study of the crystallization and the calculation of the unit-cell constants were determined by the technique of X-ray diffraction of polycrystalline samples. It was determined that the compound crystallizes in a monoclinic system with space group P21/c [No. 14] and the constants of the unit cell a = 11.958 (3), b = 9.675 (4), c = 12.661 (4) Å, β = 96.960° (2), V = 1454.01 (Å3).
