YieldReaction ConditionsOperation in experiment
60% With sodium hydroxide; In ethanol; water;Reflux; To a solution of8.3 g (208 mmol) of sodium hydroxide in 50 mL of waterwas added a solution of 10 g (49 mmol) of <strong>[1082-19-5]2-cyano-1,10-phenanthroline</strong> in 100 mL of 95% ethanol. The mixturewas heated to reflux under magnetic stirring. The disappearanceof <strong>[1082-19-5]2-cyano-1,10-phenanthroline</strong> was followedby TLC with dichloromethane/methanol (95/5 v/v) as eluent.The reaction was stopped when complete disappearance of <strong>[1082-19-5]2-cyano-1,10-phenanthroline</strong>was achieved (ca. 1.5 h). The ethanol was removed under reduced pressure, andthe mixture was acidified with 37% hydrochloric acid to pH≈2 in an ice-water bath. A palebrown solid precipitated, was collected by suction filtration, washed with 10% hydrochloricacid solution and dried over vacuum to yield a pale brown solid (7.7 g, 60% yield). Theproduct was used without further purification.
