Reaction Steps

To a solution of 2,7-dichloromethyl-3,6-di-t-butylfluorene (0.75 g, 2.0 mmol) in THF (15 ml) was added a small portion of LiAlH4 (220 mg, 5.8 mmol) under stirring and the mixture was refluxed for 4 hours. The reaction was quenched with water and NaOH and extracted with ether. The ether solution was evaporated under vacuum to give a white solid of 2,7-di-methyl-3,6-di-tert-butyl-fluorene with a yield of 85%.
