5.0 g (13.0 mmol) 6-(4-Bromo-butoxy)-3,4-dihydro-2H-quinoline-1-carboxylic acid tert-butyl ester were treated with 3.66 g (51.5 mmol) N-allyl-methylamine in 100 ml DMF at 50° C. for 30 min. The mixture was concentrated in vacuo, dissolved in Et2O and water. The inorganic layer was extracted with Et2O, and the combined organic phases were washed with water and dried over Na2SO4. Purification by column chromatography on silica gel with CH2Cl2/MeOH 10:1 yielded 3.6 g (74%) 6-[4-(Allyl-methyl-amino)-butoxy]-3,4-dihydro-2H-quinoline-1-carboxylic acid tert-butyl ester as light yellow oil, MS: 375 (MH+).
