1 g tin (II) chloride-dihydrate was added to 290 mg (1-benzyl-piperidin-4-yl)-(2-nitro-benzyl)-amine in 18 mL ethanol. The reaction was refluxed for 15 min. DMF was added until the reaction was diluted. Then, 5 mL 10 M HCl in ethanol was added, the solvent was removed, 8 mL acetone was added and the mixture was stirred at RT. The precipitate was filtered to give 550 mg of the desired product. Rf: 0.35 (dichlormethane 9: methanol 1: ammonia 0.1), (M+H)+: 296
