Versuchsvorschrift

Hydrogenolysis of the tert-butyl 2-(2-iodooxazol-4-yl)benzylcarbamate was performed using H-Cube, 10% Pd/C, full H2 Mode, at 25° in EtOH. Following completion the reaction was concentrated and the residue was purified via Biotage (0% to 10% gradient; EtOAc:Hex; 50 g-HP-silica gel column). Obtained 200 mg of tert-butyl 2-(oxazol-4-yl)benzylcarbamate. 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 1.47 (s, 9H) 4.39 (s, 2H) 7.36 (ddd, J=7.26, 5.37, 1.77 Hz, 2H) 7.48-7.65 (m, 2H) 7.89 (d, J=1.01 Hz, 1H) 8.00 (s, 1H); MS[MH]+=275.2
