Procedure

Potassium t-butoxide (30.6 g, 275.0 mmol) is added to a solution of 4-methoxybenzenethiol (30.0 ml, 250.0 mmol) in 250 ml of DMF. The mixture is heated at 80° until homogeneous, after which 2-bromobutane (30.0 ml, 275.0 mmol) in 30 ml of DMF is added dropwise over approx. 30 min. The mixture is stirred at 60° overnight after which it is cooled and is then poured into water and the aqueous phase is extracted with ether (3X). The combined ether extracts are washed with water, with 5% sodium hydroxide, with water and with brine, dried and the solvent removed to give 4-(1-methylpropylthio)anisole.
