Reaction Steps

A solution of 3.9 g of (RS)-2-(2-oxoethyl)-6-methoxy-3,3-diethyl-1-indanone and 120 mg of p-toluenesulfonic acid in 100 ml of anhydrous toluene was heated on a water separator. A solution of 4.5 g of (R)-1-amino-2-propanol in 30 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/hexane 1:1). 2.73 g (61%) of (R)-1-(7-methoxy-4,4-diethyl-1,4-dihydro-indeno[1,2-b]pyrrol-1-yl)-propan-2-ol were obtained as a red-brown oil.
