YieldReaction ConditionsOperation in experiment
92% With sodium hydroxide; In water; at 100℃; for 15.0h; Example 26A 3-chloro-6-phenoxypyridazine 3,4-Dichloropyridazine (Aldrich, 4.47 g, 30 mmol) in NaOH (10%, 20 mL) was treated with phenol (Aldrich, 1.88 g, 20 mmol) at 100 C. for 15 hours. After cooling to room temperature, the mixture extracted with ethyl acetate (2*50 mL). The extracts were combined and concentrated under reduced pressure. The title compound was purified by chromatography (SiO2, Hexanes:ethyl acetate=80:20, Rf. 0.5) as a solid (3.8 g, yield, 92%). 1H NMR (CDCl3, 300 MHz) δ 7.11-7.29 (m, 3H), 7.38-7.55 (m, 4H) ppm. MS (DCl/NH3) m/z 207 (M+H)+, 209 (M+H)+.
