Reaction Steps

2,6-Dichloro-3-nitropyridine (0.222 g, 1.15 mmol), 4-aminotetrahydropyran (0.109 g, 1.08 mmol) and DIEA (0.300 mL, 1.72 mmol) were taken up in ethanol (3.0 mL) and heated to 175° C. for 15 minutes in a heavy walled sealed tube under microwave irradiation. The solvent was removed under reduced pressure and the residual solid was purified by preparative HPLC to give the title compound (0.186 g). LCMS m/z=258.3 [M+H]+; 1H NMR (400 MHz, CDCl3) δ ppm 1.60-1.75 (m, 2H), 2.8 (d, J=12.4 Hz, 2H), 3.60 (t, J=11.4 Hz, 2H), 4.02 (d, J=11.8 Hz, 2H), 4.30-4.45 (m, 1H), 6.63 (d, J=8.6 Hz, 1H), 8.29 (d, J=5.8 Hz, 1H), 8.35 (d, J=8.6 Hz, 1H).
