Reaktionsschritte

To a solution of 2-imidazole carboxaldehyde (1.00 g, 10.4 mmol) in DMF (1 mL) was added 1 eq. tert-butylbromoacetate, potassium carbonate and a catalytic amount of potassium iodide. The reactions were heated at 110° C. for 18 hrs followed by evaporation to dryness and purified utilizing a Biotage SP4 with a gradient method of 5-50% methanol in DCM to yield the desired compound (850 mg, 4.03 mmol, 39% yield). 1H NMR (400 MHz, DMSO-d6) δ 7.6 (s, H), 7.23 (s, H), 5.15 (s, 2H), 1.40 (s, 9H).
