3.64 g (9.7 mmol) 6-[4-(Allyl-methyl-amino)-butoxy]-3,4-dihydro-2H-quinoline-1-carboxylic acid tert-butyl ester in 5 ml CH2Cl2 were treated with 3.5 ml TFA at 0° C., and the solution was stirred at 40° C. for 1 h. The solution was concentrated and the residue dissolved in a mixture of a saturated aqueous solution of NaHCO3 and ether. The inorganic phase was extracted with ether and the combined organic phases were washed with water and dried over Na2SO4 to yield 1.85 g (69%) Allyl-methyl-[4-(1,2,3,4-tetrahydro-quinolin-6-yloxy)-butyl]-amine, MS: 275 (MH+).
