Procedure

A solution of 4-(2-(4-nitronaphthalen-1-yloxy)ethyl)pyridin-3-amine (17) (700 mg, 2.263 mmol) in a mixture of MeOH (50 mL), EtOAc (25 mL), and DCM (25 mL) was passed through a Thales H-cube (10% Pt/C 30 mm, 1.0 mL·min−1, at 40° C., full hydrogen mode). The solvent was removed in vacuo to give 4-(2-(4-aminonaphthalen-1-yloxy)ethyl)pyridin-3-amine (18) as a brown solid (612 mg, 92%). m/z 280 (M+H)+ (ES+).
