m-Chloroperbenzoic acid → HCID 89963242, compound

Participants

Reaction Steps

To a solution of the 4-(cyclohex-1-en-1-yl)pyridazine (0.15 g, 0.94 mmol) prepared in Example 53a in dichloromethane (9.4 mL), 3-chloroperbenzoic acid (0.76 g, 3.09 mmol) was added with cooling on ice, and the reaction solution was stirred at room temperature for 4 hours. A highly polar compound was removed with a silica gel pad (dichloromethane) to yield crude epoxide. A solution of the crude epoxide and Raney nickel in ethanol (3.0 mL) was stirred at 70° C. for 3 hours under a hydrogen atmosphere. The reaction solution was filtered, and the residue was then purified with silica gel chromatography to yield the title compound (35 mg, 31%) as a colorless amorphous solid.
