pent-4-yn-1-amine;hydrochloride

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Pent-4-yn-1-amine hydrochloride (5.48 g, 45.8 mmol) was added to a 6° C. solution of 2,4-dichloro-3-nitroquinoline (10.6 g, 43.6 mmol) and triethylamine (15.2 mL, 109 mmol) in dichloromethane (100 mL). After 30 minutes, the solution was allowed to warm to room temperature. After 5 hours, the volatiles were removed under reduced pressure and the solid residue was triturated with water and isolated by filtration. The filter cake was rinsed with water and toluene and was allowed to dry for several days to yield 2-chloro-3-nitro-N-pent-4-ynylquinolin-4-amine as an orange solid (13.16 g). After 5 hours the volatiles were removed under reduced pressure the solid residue was triturated with water isolated by filtration The filter cake was rinsed with water and toluene to dry for several days
