Reaction Steps

A solution of 2.88 g of (RS)-2-(2-oxoethyl)-5-fluoro-1-indanone and 100 mg of p-toluenesulfonic acid in 90 ml of anhydrous toluene was heated on a water separator. A solution of 4.51 g of (R)-1-amino-2-propanol in 20 ml of anhydrous toluene was added dropwise to the boiling solution over a period of 5 minutes. Subsequently, the mixture was boiled for an additional 45 minutes, during which the solvent was reduced to a volume of 20 ml. The cooled reaction mixture was purified by column chromatography on silica gel (ethyl acetate/toluene 1:1). 2.75 g (79%) of (R)-1-(6-fluoro-1,4-dihydro-indeno[1,2-b]pyrrol-1-yl)-propan-2-ol were obtained as a brown oil.
