Reaction Steps
In a dry 3-necked flask under argon at -50° C., n-butyl lithium (0.0025 M, 0.021 ml) was added to 150 ml diethylether. Then 4.16 grams 3-bromoquinoline in 2 ml THF was added dropwise while stirring and maintaining the temperature at -60° C. to -55° C. The solution was stirred for 30 minutes, and 2.3 grams N-methyl-N-methoxybutanamide were then added dropwise at -50° C. and the solution was stirred an additional 30 minutes The solution was then allowed to warm to 0° C. and stirred for one hour. The reaction was quenched with a saturated solution of ammonium chloride and the THF layer separated, washed with brine, separated, and dried over magnesium sulfate. Filtration through diatomaceous earth, followed by concentration and subsequent thin layer chromatography (35% ethylacetate/65% CH2Cl2) gave a total yield of 2.03 g (51%) of the title compound.
