Reaction Steps

A solution of 4-(3-aminopropyl)-1-methylpiperazine (3.1 mL, 20 mmol) in MeOH (50 mL) was cooled in an ice bath and treated with ethyl glyoxylate (50% solution in toluene, 5.6 mL, 27 mmol) and AcOH (3 mL). After stirring for 15 min, NaBH3CN (1.37 g, 21.8 mmol) was added and the mixture was allowed to stir for 7 h while slowly warming to room temperature. The mixture was diluted with saturated aqueous NaHCO3 (150 mL) and then extracted with EtOAc (3×100 mL) followed by CH2Cl2 (3×100 mL). The combined CH2Cl2 layers were dried over Na2SO4, filtered and the solvent was removed in vacuo to give the title compound (1.81 g, 38%) as a colorless oil: MS (ESI) m/e 244 (M+H)+.
