Procedure

To a solution of 3-ethyl-4-methoxybenzonitrile (8-2, 0.12 g, 0.71 mmol) in MeOH (3.5 mL) was added Pearlman's Catalyst (0.020 g, 0.036 mmol) and concentrated HCl (0.47 mL, 5.71 mmol). The system was then stirred under an atmosphere of hydrogen via a balloon overnight. The reaction contents were filtered through a pad of celite and solvents were removed in vacuo to yield the desired product (8-3) as a salmon colored crystalline solid in the form of a mono HCl salt. ESI+ MS [M+H]+ C8H12N2O2: M-16 (—NH2), 149.07 found, 149.2 required.
