Reaction Steps

7-(9H-Fluoren-2-yl)-7,9-diaza-bicyclo[4.2.2]dec-3-ene-8,10-dione (310 mg, 0.94 mmol) in THF (4 mL) was placed in a μW tube. Dibal-H (4 mL, 4 mmol, [1M] in THF) was then added to the reaction mixture with venting under argon flow. When all H2 evolution was completed, the reaction mixture was heated to 130° C. for 900 sec. The reaction mixture was then diluted with a saturated Rochelle's solution (30 mL) and diethyl ether (30 mL) followed by stirring vigorously overnight. The layers were separated and the organic solution was dried with magnesium sulfate, filtered and the solvent removed by reduced pressure to yield the title compound as a residue.
