6-Chloro-4-phenyl-2-piperidin-1-yl-quinoline-3-carboxylic acid hydrazide (prepared as described in example 77 step E) (35 mg, 82.7 μmol, Eq: 1.00) and 1,1′-thiocarbonyldiimidazole (17.7 mg, 99.2 μmol, Eq: 1.2) were dissolved in THF (1.00 ml). Then triethylamine (11.7 mg, 16.1 μl, 116 μmol, Eq: 1.4) was added and the mixture was warmed to 50° C. for 72 h. Water was added and the mixture was extracted with ethyl acetate (3×). The combined extracts were washed with water and brine, dried with Na2SO4 and evaporated. The remaining residue was purified by column chromatography (silica gel, DCM/EtOAc 97:3) to afford the title compound as yellow solid (28 mg). MS (ESI): 423.1 (M+H)+.
