Procedure

Under a nitrogen atmosphere THF (90 mL) and triethylamine (17.5 mL, 125.6 mmol) were added sequentially to a mixture of crude 4-chloro-3-nitroquinoline (13.10 g, 62.81 mmol) and 1-tetrahydro-2H-pyran-4-ylmethylamine hydrochloride (10.0 g, 65.95 mmol). The reaction mixture was placed in an oil bath at 45° C. for 1 hour and then concentrated under reduced pressure. The residue was diluted with THF (30 mL) and water (200 mL). The THF was removed under reduced pressure. A solid was isolated by filtration and dried to provide 16.10 g of 3-nitro-N-(tetrahydro-2H-pyran-4-ylmethyl)quinolin-4-amine as a light yellow solid.
