A 200 ml round bottom flask was charged with 2,4-dichloro-3-nitro-5,6,7,8-tetrahydroquinoline (10 g, 0.04 mol), triethylamine (6.1 g, 0.06 mol, 1.5 equivalents) and anhydrous N,N-dimethylformamide (100 mL). To this solution was added 2-(3-pyridin-3-ylpropoxy)ethanamine (7.3 g, 0.04 mol). The reaction mixture was heated to 55° C. and maintained overnight with stirring. The reaction was quenched by pouring into water (1000 mL). The reaction mixture was then extracted with a 1:1 solution of hexane/ethyl acetate (4×200 mL). The organics were combined, washed with brine (300 mL) and concentrated to provide 2-chloro-3-nitro-N-[2-(3-pyridin-3-ylpropoxy)ethyl]-5,6,7,8-tetrahydroquinolin-4-amine as an orange syrup (14.8 g, 94%). TLC (10% MeOH/CH2CL2, Rf=0.84).
