90 °C

A mixture of 6-bromo-4-chloroquinoline-3-carboxamide (50 g, 175.4 mmol), tetrahydro-2H-pyran-4-amine (26.2 g, 193 mmol) and DIPEA (56.13 mL, 438.5 mmol) in DMA (500 mL) was stirred at 90° C. overnight. The mixture was allowed to cool and poured into water (1500 mL). The precipitate was filtered, washed with water (2×200 mL) and dried under reduced pressure to afford the desired material (57.3 g, 93%) as a white solid. NMR Spectrum: 1H NMR (400 MHz, DMSO-d6) δ 2.88-1.92 (2H, m), 2.59-2.78 (2H, m), 3.50-3.62 (3H, m), 3.96-4.08 (2H, m), 4.92-4.98 (1H, m), 7.80 (1H, m), 7.99 (1H, dd), 8.46 (1H, d), 8.74 (1H, s).
