Triethylamine → HCID 86626639, compound

Participants

Reaction Steps

Triethylamine (8.0 mL, 1.2 eq.) was added to a mixture of 4-chloro-3-nitroquinoline (10.0 g, 47.9 mmol, 1.0 eq.) in tetrahydrofuran (THF, 200 mL). Propargylamine (3.4 mL, 1.1 eq.) was added and the reaction mixture was stirred vigorously for 1.5 hours. The reaction mixture was concentrated under reduced pressure and the residue was partitioned between chloroform (700 mL) and water (200 mL). The organic layer was washed with water (1×200 mL). The combined aqueous layers were back extracted with chloroform (2×150 mL). The combined organics were dried over magnesium sulfate and concentrated under reduced pressure to provide 10.59 g of 4-chloro-3-nitro-N-(2-propynyl)quinoline as a yellow solid.
