Sodium freed from encrustation (5.75 g, i.e. 0.25 g-atom) was added to 100 ml of dry toluene (Note 1) contained in a 250-ml three-necked round-bottomed flask fitted with stirrer, dropping funnel, and reflux condenser protected by a calcium chloride tube. The mixture was heated until the sodium melted, and the stirrer was then set into motion and the application of heat was stopped; vigorous stirring was continued for 10–15 minutes, during which the temperature of the mixture fell to 40–50°. Gentle stirring of the toluene suspension of finely granulated sodium was continued at this temperature while 30 g (0.33 mole) of freshly distilled 1-butanethiol (Note 2) was added dropwise; the mixture was allowed to stand for several hours.
