Reaction Steps
To a 25 mL glass vial is added 6-cyclopropyl-5-(2-fluoro-4-nitrophenoxy)-2-(tetrahydro-2H-pyran-2-yl)-2H-indazole (395 mg, 994 μmol) and MeOH (20 mL, 494 mmol). To the suspension is added N,N-dimethylhydrazine (756 μL, 9.94 mmol) and FeCl3 (163 mg, 994 μmol). The vial is capped, and heated to 60° C. and stirred for 2 hours and then stirred at 50° C. overnight. The mixture is filtered over a Buchner funnel and the solid washed with MeOH (100 mL). The filtrate is collected and concentrated to give a brown/orange solid. The residue is purified on a silica gel column eluting with DCM (A) and a 10% MeOH in a DCM solution (B), gradient from 100% (A) to 85%(A): 15%(B) over 50 min to give a yellow solid as the title compound (358 mg, 98% yield). MS (m/z): 368 (M+H).
