Procedure

Combine 2-carboethoxy-4,6-dichloroindole (1.43 g, 5.0 mmol), pyrid-2-ylacetonitrile (0.59 g, 5.0 mmol), piperidine (0.2 mL), and ethanol (30 mL). Heat to reflux. After 16 hours, cool to ambient temperature. Add diethyl ether to give a solid. Filter, rinse with diethyl ether, dry, recrystallize from acetone/water, filter, and dry to give the title compound: mp; 250-254° C. (dec). 1H NMR (DMSO-d6) δ 12.9 (br s, 1H), 8.86 (s, 1H), 8.70 (d, 1H, J=1 Hz), 8.00 (m, 1H), 7.82 (d, 1H, J=7.2 Hz), 7.55 (s, 1H), 7.48 (m, 1H), 7.48 (m, 1H), 7.34 (s, 1H), 4.35 (q, 2H, J=7.1 Hz), 1.25 (t, 3H, J=7.1 Hz).
