Reaction Steps

2-Chloroquinoline-3-carbaldehyde (0.27 grams, 1.40 mmol) and potassium carbonate (0.579 grams, 1.4 mmol) were added to a 25 mL two-necked round bottomed flask. To this flask was added 3 mL of N,N-dimethylformamide (DMF), followed by the drop-wise addition of a dimethylformamide solution of cyclopentyl methyl ethyl amine (0.214 grams, 1.69 mmol). The resulting mixture was refluxed for 2 hours and then cooled to 25-35° C., after which the mixture was poured onto crushed ice (10 mL), and extracted with ethyl acetate (3×50 mL). The organic layer was washed with brine and dried over sodium sulfate. The solvent was evaporated in vacuo to provide the product as yellow oil (0.355 g, yield: 89%).
