Reaction Steps
3-(2-Methoxy-ethoxy)-2-nitro-5-phenoxy-pyridine (0.4 mmol) is dissolved in acetic acid (1.3 ml). After addition of water (1.3 ml), zinc powder (6 eq.) is added and the reaction suspension is heated to 100° C. for 3 h. The reaction suspension is cooled to room temperature and filtrated. The filtrate is pored into 3.5% NaOH (30 ml) and extracted with dichloromethane. The combined organic layers are extracted with brine, dried over MgSO4 and the solvent is removed in vacuo. 3-(2-Methoxyethoxy)-5-phenoxy-pyridine-2-ylamine is obtained as brown oil in a yield of 76%. HPLC (method C): 1.43 min; LC-MS (method A): 0.808 min, 261.15 (M+H+).
