Versuchsvorschrift

Chloroacetone (11.6 g, 125 mmol) and NaHCO3 (12.6 g, 150 mmol) were added to a solution of 4-methylthiophenol (10 g, 80.5 mmol) in dry DMF (50 mL). The mixture was stirred at 50-60° C. for 1 h. The cooled reaction mixture was poured into water (200 mL) and extracted with EtOAc (2×50 mL). The combined organic extracts were dried with K2CO3, evaporated to dryness and the residue was distilled (b.p. 145-148° C./12 mm) to give 11.7 g of 1-(p-tolyl sulfanyl)propan-2-one (81%).
