Reaktionsschritte
5-Methoxy-2-oxo-1-(1-t-butoxycarbonylpiperidin-4-yl)-2,3-dihydro-1H-imidazo[4,5-b]pyridine (100 mg, 0.287 mmol) was dissolved in methanol (2.5 mL) and a solution of 2N hydrochloric acid in ether (3 mL) was added at room temperature. After 2 h, the volatiles were removed in vacuo, to give the title compound (61 mg). MS 249.1 (M+1).
