Versuchsvorschrift

2-Aminomethylpyridine (55.9 ml, 546 mmol) was added to a solution of 1-(3-chloro-5-oxo-5H-benzo[4,5]cyclohepta[1,2-b]pyridin-7-yl)-N-methyl-N-phenylmethanesulfonamide (51.6 g, 121 mmol) in N-methyl-2-pyrrolidinone (1214 ml) at room temperature. The solution was then heated to 130-135° C. for 2 h in a pre-warmed oil bath. The solution was then cooled to room temperature and poured into aqueous sodium hydrogen carbonate (saturated, 3.0 L) and 500 mL ice-water and extracted with ethyl acetate (3×500 mL). The combined organics were dried over anhydrous Na2 SO4, filtered and concentrated under reduced pressure. The residue was purified by column chromatography on silica gel (EtOAc/Hexanes gradient) to afford the title compound as a yellow solid. 1H NMR (600 MHz, DMSO-D6) δ 8.99 (d, 1H); 8.47 (d, 1H); 8.46 (m, 1H); 8.16 (d, 1H); 7.81 (m, 3H); 7.76 (m, 1H); 7.49 (d, 1H); 7.38 (d, 1H); 7.32 (d, 1H); 7.25 (m, 1H); 4.63 (s, 2H); 4.22 (d, 2H). LRMS (APCI) calculated for C21H17ClN3O3S [M+H]+, 426.1; found 426.0.
