Reaction Steps

The title compound (27 mg, 55%) was synthesized from 1-(3-(quinolin-6-ylmethyl)-[1,2,4]triazolo[4,3-b]pyridazin-6-yl)ethanone (40 mg, 0.132 mmol) and 1-methylhydrazine-carboxamide (23.5 mg, 0.264 mmol) using the same procedure as described in the synthesis of 37. 1H-NMR (400 MHz, DMSO-d6) δ ppm 9.06 (d, 1H), 8.73 (d, 1H), 8.17 (m, 4H), 8.00 (d, 1H), 7.79 (m, 1H), 6.69 (s, 2H), 4.82 (s, 2H), 3.27 (s, 3H), 2.32 (s, 3H). LCMS (method A): [MH]+=375.0, tR=3.79 min.
