Reaction Steps

To a solution of 1′-{[1-(4-bromophenyl)cyclobutyl]carbonyl}-3H-spiro[furo[3,4-c]pyridine-1,3′-pyrrolidin]-3-one (30 mg, 0.00007 mol), and 1H-benzimidazole (0.010 g, 0.000087 mol) in toluene (0.5 mL, 0.005 mol) and N,N-dimethylformamide (0.5 mL, 0.006 mol), were added (1S,2S)-N,N′-dimethylcyclohexane-1,2-diamine (2.1 mg, 0.000014 mol), copper(I) iodide (1 mg, 0.000007 mol), and potassium carbonate (21.1 mg, 0.000152 mol), and the mixture was stirred at 120° C. overnight. The reaction mixture was then filtered and the filtrate was dilluted with methanol. The product was purified using prep-HPLC followed by chiral HPLC. LC-MS: 465.2 (M+H)+.
