실험 절차

(R)-tert-Butyl 3-(1-(3-methoxypropyl)-1H-benzo[d]imidazol-2-yl)piperidine-1-carboxylate (4.82 mmol; 1.8 g) was added to a 100 mL round-bottomed flask equipped with a reflux condenser and stirring under nitrogen. EtOH (15 mL) and HCl (8 M in H2O; 4 mL) were then added and the solution was heated to reflux for 10 min. Analysis of the reaction mixture by LC/MS indicated that the reaction was complete. The solvent was then removed in-vacuo. The resultant oil was then extracted with EtOAc and a 10% aqueous K2CO3 solution. The organic layer was collected and dried with Na2SO4, and was then filtered. The filtrate was concentrated and dried in-vacuo affording (R)-1-(3-methoxypropyl)-2-(piperidin-3-yl)-1H-benzo[d]imidazole (7D) as a brown oil (4.76 mmol, 1.3 g, 99% yield). ESI-MS: m/z 274.4 (M+H)+.
