Reaction Steps

3-Chloro-N,N-diethylpropan-1-amine (1.6 g) is added to a mixture of tert-butyl piperazine-1-carboxylate (2.0 g) and NEt3 (1.5 ml) in methanol (30 ml). The mixture is stirred for 6 hours at 70° C. and cooled to room temperature. The solvent is removed under reduced pressure. Satd. aqueous NaHCO3 is added to the crude product and the aqueous layer is extracted with EtOAc (3×). The combined organic layers are dried (Na2SO4) and filtered, and the solvent is removed under reduced pressure to give tert-butyl 4-(3-(diethylamino)propyl)piperazine-1-carboxylate (2.48 g). m/z(+) 300 (M+H+).
