Reaction Steps

Fluorene-1-carboxylic acid was purchased from Aldrich. It was reduced as described in J. Am. Chem. Soc. 1961, 83, 417 via the methyl ester to 1-hydroxymethylfluorene 1H NMR (CDCl3): δ 4.84 ppm (CH2), 3.89 ppm (CH2). 4.1 g (21 mmol) 1-hydroxymethylfluorene dissolved in 60 ml THF was slowly added to 2.54 g PBr3 in 10 ml THF at −5° C. The orange solution was stirred for 1.5 hrs at −5° C. then stirred for 16 hrs at room temperature. This was then poured into iced water, allowed to settle and 5.1 g of 1-bromomethylfluorene was isolated on a frit as an off-white powder. 1H NMR (CDCl3): δ 4.65 ppm (CH2), 3.97 ppm (CH2).
