Procedure

A solution of 1-(3-(quinolin-6-ylmethyl)-[1,2,4]triazolo[4,3-b]pyridazin-6-yl)ethanone (41.2) (40 mg, 0.132 mmol) and 2-(aminooxy)propan-1-ol (intermediate Q) (33.6 mg, 0.264 mmol) in 15 mL of MeOH was stirred at it overnight. Solvent was evaporated and the crude was purified by HPLC (basic with 0.05% NH4OH) to give 22 mg (44%) of the title compound as a white solid. 1H-NMR (400 MHz, MeOH-d4 δ ppm 8.82 (s, 1H), 8.33 (d, 1H), 8.12 (d, 1H), 7.98 (t, 3H), 7.84 (d, 1H), 7.55 (m, 1H), 4.84 (s, 2H), 4.50 (m, 1H), 3.72 (d, 2H), 2.32 (s, 3H), 1.33 (d, 3H). LC-MS (method B): [MH]+=377.0, tR=1.867 min.
