2-(2-chloro-4-fluorophenyl)acetamide (400 mg, 2.13 mmol) was diluted with THF (2 mL), placed under nitrogen and cooled to 0° C. LAH (4264 μL, 4.26 mmol) was added dropwise and the reaction was refluxed for 3 hours. The reaction was cooled to 0° C. and quenched with 160 μL of water, 160 μL of 15% NaOH, and 530 μL of water. After stirring for 30 minutes the reaction was filtered and concentrated. The material was purified using a biotage 25 column eluting with 2% NH4OH/10% methanol/DCM to yield 2-(2-chloro-4-fluorophenyl)ethanamine (60 mg, 0.346 mmol, 16.2% yield).
