Crystal structure of methyl (E)-2-(4-(diethylamino)-2-hydroxybenzylidene)hydrazine-1-carboxylate, C₁₃H₁₉N₃O₃

Abstract

CCDC no.: 1522954The asymmetric unit of the title crystal structure is shown in the figure. Tables 1 and 2 contain details of the measurement method and a list of the atoms including atomic coordinates and displacement parameters. Source of materialsMethyl hydrazinecarboxylate (0.9 g, 10 mmol) and 4-diethylamino-2-hydroxybenzaldehyde (1.93 g, 10 mmol) were dissolved in stirred methanol (25 mL). The reaction mixture was refluxed for 7-8 h with TLC monitoring (ethyl acetate:hexane = 1:1). The resulting solid was filtered off and recrystallized from ethanol to give the title compound.
