A flask charged with 5-(7-azabicyclo[2.2.1]heptan-7-yl)-2-nitrobenzonitrile 22 (205 mg, 0.8427 mmol) and 10% Pd/C (41 mg, 0.39 mmol) was flushed with nitrogen and then evacuated under vacuum. Methanol (4 mL) was added under nitrogen atmosphere and the flask was fitted with a hydrogen balloon. After stirring for 15 min, the Pd/C was removed by filtration and solvent was removed under reduced pressure to provide 2-amino-5-(7-azabicyclo[2.2.1]heptan-7-yl)benzonitrile 23 (170 mg, 95% yield). 1H NMR (400.0 MHz, DMSO-d6) δ 7.02 (dd, J=2.8, 9.0 Hz, 1H), 6.87 (d, J=2.7 Hz, 1H), 6.68 (d, J=9.0 Hz, 1H), 5.36 (s, 2H), 4.09 (s, 2H), 1.59 (d, J=6.8 Hz, 4H), 1.34 (d, J=6.8 Hz, 4H).
