Participants

Reaction Steps

The title compound (12 mg, 28.6%) was synthesized from 2-(1,3-dihydroxypropan-2-yloxy)isoindoline-1,3-dione (intermediate B) (152 mg, 0.643 mmol, isomer mixture), hydrazine monohydrate (14 mg, 0.27 mmol) and 1-(3-(quinolin-6-ylmethyl)-[1,2,4]triazolo[4,3-b]pyridazin-6-yl)ethanone (41.2) (30 mg, 0.11 mmol) using the same procedure as described in the synthesis of example 44. After purification by HPLC (acidic with 0.05% TFA, then neutralized to basic), the title compound was obtained as a white solid. 1H-NMR (400 MHz, CDCl3) δ ppm 8.89 (d, 1H), 8.12 (d, 1H), 8.08 (d, 1H), 7.97 (d, 1H), 7.86 (s, 1H), 7.82 (d, 1H), 7.73 (d, 1H), 7.42 (m, 1H), 4.77 (s, 2H), 4.49 (m, 1H), 4.00 (dd, 4H), 2.33 (s, 3H). LC-MS (method B): [MH]+=393.2, tR=1.708 min.
