Versuchsvorschrift

To a solution of 5-methyl-4-oxo-1,4-dihydroquinoline-3-carboxylic acid 35 (162 mg, 0.80 mmol) and 2-amino-5-(7-azabicyclo[2.2.1]heptan-7-yl)benzonitrile 23 (170 mg, 0.80 mmol) in 2-methyltetrahydrofuran (1.5 mL) was added propyl phosphonic acid cyclic anhydride (50% solution in ethyl acetate, 949.5 μL, 1.605 mmol) and pyridine (126 mg, 129 μL, 1.60 mmol). The reaction was capped and heated at 100° C. for 65 min with microwave irradiation. The reaction was cooled to room temperature, diluted with ethyl acetate (10 mL), and quenched with saturated Na2CO3 solution (6 mL). The organic layer was dried over Na2SO4, filtered and concentrated. Purification by silica gel chromatography (0-35% ethyl acetate in dichloromethane) provided N-(4-(7-azabicyclo[2.2.1]heptan-7-yl)-2-cyanophenyl)-5-methyl-4-oxo-1,4-dihydroquinoline-3-carboxamide (157 mg, 49% yield). LC/MS m/z 399.3 [M+H]+, retention time 1.47 min (RP—C18, 10-99% CH3CN/0.05% TFA over 3 min). 1H NMR (400.0 MHz, DMSO-d6) δ 12.77 (s, 1H), 12.75 (s, 1H), 8.77 (s, 1H), 8.11 (d, J=9.1 Hz, 1H), 7.64-7.60 (m, 1H), 7.55 (d, J=8.0 Hz, 1H), 7.34 (d, J=2.8 Hz, 1H), 7.27 (dd, J=2.8, 9.1 Hz, 1H), 7.23 (d, J=7.2 Hz, 1H), 4.32 (s, 2H), 2.91 (s, 3H), 1.65 (d, J=7.2 Hz, 4H), 1.42 (d, J=6.8 Hz, 4H).
