참여 물질

반응 단계

Mix 3-chloro-4-fluorobenzaldehyde (3.28 g, 20.7 mmol), 4-hydroxybenzamide (3.12 g, 22.7 mmol), potassium carbonate (4.29 g, 31.0 mmol) and dimethylacetamide (80 mL) in a flask. Heat the reaction to 100° C. for 3 hours. Let cool to ambient (room) temperature and pour into water (200 mL). After trituration, filter the solid formed and dry on a vacuum pump to obtain the product (5.35 g, 94%). 1H NMR (DMSO-d6) 9.94 (s, 1H), 8.13 (d, J=1.7 Hz, 1H), 7.98 (bs, 1H), 7.94 (d, J=8.5 Hz, 2H), 7.88 (dd, J=1.7 Hz, 8.5 Hz, 1H), 7.36 (bs, 1H), 7.21 (d, J=8.5 Hz, 1H), 7.14 (d, J=8.5 Hz, 2H).
