Abstract

<abstract abstract-type="normal"> <title> <x content-type="archive" xml:space="preserve">Abstract</x> </title> <p>The title compound 1-<italic>N</italic>-(3-pyridylmethyl)aminonaphthalene hydrochloride (C₁₆H₁₅N₂Cl) was obtained by a reaction of <italic>α</italic>-naphthylamine (<bold>1</bold>) and <italic>N-</italic>pyridincarboxaldehyde (<bold>2</bold>) in anhydrous ethanol in the first step. The formed imine (<bold>3</bold>) was reduced with sodium borohydride in anhydrous methanol to give the product 1-<italic>N</italic>-(3-pyridylmethyl)aminonaphthalene (<bold>4</bold>). Finally, the hydrochloride was prepared by addition of a hydrochloric acid–ethyl acetate solution (ratio 1:3) with constant stirring and maintaining the temperature between 0 and 5 °C, obtaining a yellow polycrystalline solid corresponding to the respective derivative (<bold>5</bold>). The X-ray powder diffraction pattern for the new compound (<bold>5</bold>) was obtained. The compound (<bold>5)</bold> crystallizes in a monoclinic system with the space group <italic>P</italic>2₁/<italic>m</italic> (No. 11) and refined unit-cell parameters: <italic>a</italic> = 16.257 (8) Å, <italic>b</italic> = 9.236 (7) Å, <italic>c</italic> = 13.221 (6) Å, <italic>β</italic> = 94.87° (5), <italic>Z</italic> = 6, and <italic>V</italic> = 1978 (1) ų.</p> </abstract>
