YieldReaction ConditionsOperation in experiment
With sodium nitrite; In water; Petroleum ether; A solution of sodium nitrite (4.5 g) in water (100 ml) was added dropwise during 5 minutes to a stirred suspension of ethyl 6-chloroanthranilate (12.7 g) in a mixture of concentrated sulphuric acid (27.9 ml), water (38 ml) and ice (76 g). The reaction mixture was stirred at 0C for an additional 20 minutes and then heated to 120C for 1 hour. The resultant mixture was poured into a mixture of ice and water and the product was extracted with diethyl ether. The organic phase was washed in turn with water and brine, dried over magnesium sulphate and evaporated. The residue was purified by column chromatography on silica using a 4:1 mixture of petroleum ether (b.p. 60-80C) and methylene chloride as eluent. There was thus obtained ethyl 6-chloro-2-hydroxybenzoate (9.8 g); NMR Spectrum : (DMSOd6) 1.3 (t, 3H), 4.3 (q, 2H), 6.9 (d, 1H), 6.95 (d, 1H), 7.25 (d, 1H), 10.45 (br s, 1H).
