4-(1H-1,2,3-Triazol-4-yl)butanoic acid (Example 17, step 4) (200 mg, 1.289 mmol) and 3,5-dichlorobenzyl 4-(methylamino)piperidine-1-carboxylate (Step 2) (456 mg, 1.289 mmol) were dissolved in DMF (6 ml) and treated with DIPEA (1.126 ml, 6.45 mmol) followed by 50% T3P® in DMF (1.505 ml, 2.58 mmol). After stirring at RT for 9 days, the mixture was evaporated under reduced pressure. The crude product was solubilised in DCM and washed with 10% citric acid. The organic portion was passed through a phase separating cartridge and the filtrate was evaporated under reduced pressure. The crude residue was purified by chromatography on silica eluting with 0-10% MeOH in EtOAc to afford the title compound;
