80 °C

A mixture of 260 mg (1.0 mmol) of 2-chloro-3-trifluoromethyl-5-bromopyridine (from Step B) and 3 mL of morpholine was heated at 80° C. for 1 h. The mixture was cooled and concentrated. The residue was partitioned between 50 mL of CH2Cl2 and 1.0 N NaOH and the layers were separated. The organics were dried and concentrated. Chromatography on a Biotage 40S cartridge using 19:1 v/v hexanes/ether as the eluant afforded 290 mg of the title compound: 1H NMR (500 MHz, CDCl3) δ 3.29 (app t, J=5.5, 4H), 3.82 (app t, J=5.5, 4H); 7.95 (d, J=2.0, 1H), 8.45 (d, J=2.0, 1H.
