Reaktionsschritte
Phenol was distilled from a boiling mixture of phenyl salicylate (42.8 gm, 0.20 mol), 2-toluidine (26.7 gm, 0.25 mol), and 1,2,4-trichlorobenzene (41 mL) as described in the literature procedure (Organic Syntheses, Coll. Vol. 3, 765). The cooled product mixture was transferred to an 250 mL Erlenmeyer flask and boiled with hexanes (75 mL) for 30 minutes. The solid product was isolated from the hot mixture by vacuum filtration. The solid was washed with more hexanes until the filtrate was colorless. Drying gave the pure 2′-methyl-salicylanilide (41 gm, 90%) as an off-white solid.
