Reaction Steps

To a solution of imidazole-2-carboxaldehyde (2.00 g, 21 mmol) in DMF (1 mL) was added 1.1 eq. of 1-bromo-2-ethoxyethane (3.51 g, 22 mmol), 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 (580 mg, 3.56 mmol, 17% yield). 1H NMR (400 MHz, DMSO-d6) δ 9.63 (s, H), 7.6 (s, H), 7.21 (s, H), 4.45 (dd, 2H), 3.62 (dd, 2H), 3.38 (m, 2H), 1.05 (t, 3H).
