To a solution of (+/−)-2-azido-4-(3-nitropyridin-4-yl)cyclohex-3-enol (1.0 equiv.) in DCM (0.15M) was added TBSCl (2.0 equiv.), imidazole (2.0 equiv.) and DMAP (0.1 equiv.) at room temperature. After 18 h, water was added, the organics were dried with brine, then Na2SO4, and concentrated. The crude material was loaded to silica gel and purified via ISCO eluting with ethyl acetate and hexanes (20%). Obtained (+/−)-4-(3-azido-4-(tert-butyldimethylsilyloxy)cyclohex-1-enyl)-3-nitropyridine as a yellow oil in 60% yield. LCMS (m/z): 376.3 (MH+), LC Rt=5.848 min.
