Reaction Steps
Method 1 was followed using trans(+/−)-3-(bis(tert-butoxycarbonyl)amino)-4-methoxypiperidine (1.0 equiv.), 4-chloro-3-nitropyridine (1.2 equiv.), and DIEA (4.0 equiv.) to give trans(+/−)-N,N-di-BOC-4-methoxy-1-(3-nitropyridin-4-yl)-piperidin-3-amine after column chromatography (EtOAc and hexanes, 50%) in 59% yield for two steps. LCMS (m/z): 453.2 (MH+), LC Rt=3.24 min.
