Procedure

A solution of 4-pentyl-cyclohexanecarboxylic acid N′-(pyridine-4-carbonyl)hydrazide (Preparation 19, 50 mg, 0.158 mmol) and Lawesson's reagent (127 mg, 0.32 mmol) in toluene (2 ml) was heated under reflux for 18 h. The solvent was evaporated and the residue purified by flash chromatography (IH-EtOAc, 4:1 then EtOAc) to afford the title compound: RT=5.02 min; m/z (ES+)=316.0 [M+H]+.
