Reaction Steps

A mixture comprising of 3,5-dichlorobenzyl 4-(2-(methylamino)ethyl)piperidine-1-carboxylate (Example 1, step 3) (100 mg, 0.290 mmol), 2-(1H-1,2,3-triazol-4-yl)acetic acid (55.2 mg, 0.434 mmol), T3P® (50% solution in DMF) (338 μl, 0.579 mmol) and Huenig's base (101 μl, 0.579 mmol) in DMF was stirred at room temperature for 18 hours. The resulting mixture was concentrated under pressure. The crude residue was diluted with water and extracted with EtOAc. The organic portion was dried over MgSO4, filtered and solvent concentrated under reduced pressure. Further purification was carried out using preparative LC-MS. The resulting product fractions were concentrated under reduced pressure to give an aqueous solution and then extracted with EtOAc. The organic extracts were dried over MgSO4, filtered and concentrated under reduced pressure to afford the title compound.
