Participants

Reaction Steps

To sodium hydride (6.6 g, 275.0 mmol; prewashed with pentane) in 100 ml of DMF, under N2 and at 5°, is slowly added ethyl mercaptan (41.0 ml, 550.0 mmol) in 50 ml of DMF. This mixture is stirred for 1.5 hours, after which is added 4-(1-methylpropylthio)anisole (46.0 g, 250.0 mmol) and DMF. The mixture is heated to 150° with stirring overnight. After cooling to 20°, 10% aqueous sulfuric acid is added and the mixture is extracted with ether. The combined organic layers are washed with water and extracted with 5% NaOH. The aqueous portion is reacidified with conc. sulfuric acid and extracted with ether. The combined ether extracts are washed with water and with brine, dried and the solvent removed to give 4-(1-methylpropylthio)phenol.
