Reaction Steps

N-Methyl-2-pyrrolidinone (3 ml) was added to N-methyl-1-[3-(1-methyl-1H-pyrazol-4-yl)-5-oxo-5H-benzo[4,5]cyclohepta[1,2-b]pyridin-7-yl]-N-phenylmethanesulfonamide (150 mg, 0.319 mmol) and pyridin-3-amine (150 mg, 1.594 mmol) in a vial. The vial was sealed and the resulting solution was heated to 180° C. with stirring. After 2.25 h., the reaction was cooled to room temperature and diluted in DMSO and water. The resulting solution was filtered and purified by preparative HPLC Reverse phase (C-18), eluting with Acetonitrile/Water+0.05% TFA, to afford the title compound as a brown solid. 1H NMR (600 MHz, DMSO-D6) δ 9.21 (d, 1H); 8.52 (d, 1H); 8.48 (s, 1H); 8.33 (d, 1H); 8.16 (d, 1H); 8.15 (s, 1H); 8.07 (s, 1H); 7.77 (d, 1H); 7.68 (dd, 1H); 7.52 (m, 1H); 7.35 (d, 1H); 7.32 (d, 1H); 7.25 (m, 1H); 4.77 (s, 2H); 3.89 (s, 3H). LRMS (APCI) calculated for C24H19N5O3S [M+H]+, 458.1. found 458.1.
