Versuchsvorschrift

Step AT2. To a solution of 4-acetamido-3,5-dichloro-benzonitrile (114 mg, 0.5 mmol) in 5 mL of THF was added lithium aluminum hydride (120 mg, 3.2 mmol) in portion and the resulting mixture was stirred for 3 hours. Sodium sulfate decahydrate (1 g, 3.2 mmol) was added in portion and the mixture was stirred for 30 minutes. The solid was filtered off and the filtration was concentrated. Residue was purified by HPLC to give 4-acetamido-3,5-dichloro-benzylamine (35 mg, 30%).
