Versuchsvorschrift

In a sealed tube, a solution of trimethylaluminum in toluene (3N, 0.41 mL, 1.23 mmol) was added to a solution of 6-fluoro-quinolin-3-ylamine (90 mg, 0.56 mmol) and 4-(3-aza-bicyclo[3.2.2]non-3-yl)-benzoic acid ethyl ester (180 mg, 0.65 mmol) in 1,2-dichloroethane (2 mL). The solution was allowed to stir at room temperature for 15 minutes, and then heated at 83° C. for 16 hours. The tube was cooled and carefully opened. Methanol (0.5 mL) was added and the resultant mixture was allowed to stir at room temperature for several hours. The mixture was diluted with dichloromethane and preabsorbed onto silica gel. Flash chromatography, using a gradient of methanol (0% to 3%) in dichloromethane as the eluant, gave the product, 60 mg (28%), as a colorless solid. MS: m/z 390.0 (MH+). 1HNMR (DMSO-d6): δ 1.67 (m, 8 H), 2.14 (m, 2 H), 3.56 (d, 2 H), 6.97 (d, 2 H), 7.54 (d of t, 1 H), 7.77 (d of d, 1 H), 7.92 (d, 2 H), 8.04 (d of d, 1 H), 8.85 (d, 1 H), 9.13 (d, 1 H) and 10.3 (s, 1 H).
