Potassium Carbonate → 4-chloro-N'-hydroxybenzenecarboximidamide

참여 물질

반응 단계

To a solution of 4-chloro benzonitrile (1.000 g, 7.26 mmol) in ethanol (20 mL) was added hydroxyl amine HCl (0.752 g, 10.90 mmol) and potassium carbonate (3.00 g, 21.80 mmol). The reaction mass was refluxed for 10-12 h. Excess of solvent was removed under vacuum and the residue was diluted with water, acidified with dilute HCl. Precipitate obtained was filtered off and sucked dried to afford 0.500 g of desired product. 1H NMR (300 MHz, DMSO d6): δ 5.88 (br s, 2H), 7.42 (d, J=8.1 Hz, 2H), 7.68 (d, J=8.4 Hz, 2H), 9.70 (br s, 1H); MS (m/z): 171.13 (M+H)+.
