Participants

Reaction Steps

Lawesson's reagent (3.20 g, 7.9 mmol) and N-(3-fluorophenyl)-N-methyl-2-pyridinecarboxamide (3.51 g, 15.2 mmol) were heated to reflux in toluene (45 mL) under nitrogen for 2 hours. The residue, after evaporation of the solvent, was dissolved in dichloromethane, preadsorbed onto silica gel, and flash chromatographed (250 g of silica gel eluted with 10% ethyl acetate in petroleum ether) to yield N-(3-fluorophenyl)-N-methyl-2-pyridinecarbothioamide, as a yellow solid (1.70 g, 45%), m.p. 100°-103° C.
