Ethanol → 1-Chloro-4-ethoxyphthalazine

Participants

Reaction Steps

Sodium (33.8 mg, 1.470 mmol) was allowed to react with EtOH (10 mL), then 1,4-dichlorophthalazine (279 mg, 1.4 mmol) was added and the reaction mixture was refluxing for 30 min. The hot solution was filtered and evaporated. The crude product was purified by silica gel chromatography eluting with 20% ethyl acetate in hexane to give 200 mg of the crude product 1-chloro-4-ethoxyphthalazine. 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 8.29-8.18 (m, 2H), 7.99-7.90 (m, 2H), 4.73 (q, J=7.1 Hz, 2H), 1.57 (t, J=7.2 Hz, 3H); MS: MS m/z 209.06 (M++1).
