1-Amino-2-propanol → HCID 19036546, compound

Participants

Reaction Steps

A solution of 1.2 g of (RS)-5-methoxy-2-(2-oxopropyl)-1-indanone and 60 mg of p-toluenesulfonic acid in 70 ml of anhydrous toluene was heated on a water separator. A solution of 1.65 g of (RS)-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 90 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 (diethyl ether/hexane 7:3). 1.17 g (82%) of (RS)-1-(6-methoxy-2-methyl-1,4-dihydro-indeno[1,2-b]pyrrol-1-yl)-propan-2-ol were obtained as a yellow solid which was used without further crystallization in the next reaction.
