Reaction Steps

Ethanolamine (4.82 mL, 80 mmol) was added to a stirred mixture of 3-chloro-5-(4-fluorophenyl)pyridazine (2.08 g, 9.97 mmol) in Dioxane (40 mL) in a sealed tube. The mixture was heated to 120° C. overnight, treated with additional ethanolamine (1.2 mL, 20 mmol), and heated to 150° C. for 2 h. The mixture was cooled and poured into ethyl acetate (100 mL) and water (100 mL). The precipitate was filtered and dried to afford the title compound. 1H NMR (500 MHz, CD3SOCD3) δ 8.76 (d, 1H); 7.78 (dd, 2H); 7.36 (t, 2H); 7.02 (d, 1H); 6.85 (t, 1H); 4.78 (t, 1H); 3.58 (q, 2H); 3.45 (q, 2H). LRMS (APCI) calc'd for (C12H13FN3O) [M+H]+, 234.1. found 234.1.
