Procedure

4-(4-Methylpiperazin-1-yl)carbonylmethylaniline (596 mg, 2.55 mmol) was treated in anhydrous THF (20 mL) under nitrogen with lithium aluminum hydride (291 mg, 2.67 mmol) overnight. The reaction was quenched with water (3×0.29 mL), 15% sodium hydroxide (3×0.29 mL) and again water (3×0.29 mL). The resulting precipitate was removed by filtration. Evaporation of the filtrate afforded the title compound as an orange oil, 380 mg.
