2-Amino-4-((4-nitronaphthalen-1-yloxy)methyl)pyridine (2) (4.50 g, 15.24 mmol) in MeOH (200 mL) and AcOH (200 mL) was passed through a Thales H-cube (2.0 mL·min−1, 40° C., 55 mm 10% Pt/C Cat-Cart, full hydrogen mode) and the volatiles were removed in vacuo. The crude product was subjected to SCX capture and release eluting with 1% NH3 in MeOH solution and the solvent was removed in vacuo to give 2-amino-4-((4-aminonaphthalen-1-yloxy)methyl)pyridine (3) (3.82 g, 94%) as a purple solid: m/z 266 (M+H)+ (ES+).
