Reaction Steps

A mixture of methyl 5-(2-(1H-imidazol-2-yl)ethoxy)-6-iodonicotinate (373 mg, 1.00 mmol), Copper(I) oxide (14.3 mg, 0.10 mmol), Ninhydrin (35.6 mg, 0.20 mmol) and potassium carbonate (290 mg, 2.10 mmol) in dimethyl sulfoxide (10.0 mL) was heated at 110° C. for 2 hours. The mixture was poured into 20 ml of water and extracted with ethyl acetate (3×15 ml). The organic extracts were washed with water (3×15 ml), brine, dried over MgSO4 and concentrated. The residue (0.220 g, 90%) was used without further purification in the next step. MS (ESI+): 246.0. 1H NMR (500 MHz, CDCl3) δ 8.77 (d, J=1.9, 1H), 8.10 (s, 1H), 8.04 (d, J=1.9, 1H), 7.08 (s, 1H), 4.47 (t, J=5.1, 2H), 3.97 (s, 3H), 3.46 (t, J=5.1, 2H).
