Procedure
s-Butyl lithium (17.7 mL of 1.3 M in hexane (0.045 mol) was added at -78° C. to a stirred solution of t-butyl 1,2,3,4-tetrahydro-5-(dipropylamino)quinoline-1-carboxylate (10 g, 0.030 mol) in THF (200 mL). After 15 minutes, methyl iodide (17.1 g, 0.13 mol) was added and the solution was allowed to warm to room temperature. The THF was removed under reduced pressure, and the residual oil was partitioned between ethyl acetate and water. The ethyl acetate was evaporated and the residual oil was chromatographed on silica gel to afford 10.65 g of t-butyl 1,2,3,4-tetrahydro-8-methyl-5-(dipropylamino)quinoline-1-carboxylate as an oil.
