The first step involved the substitution of the Br atom by using NaOMe in the presence of CuI to afford 5-methoxyindan-2-ol. The OH group of 5-methoxyindan-2-ol was converted into its mesylate ester, which was converted into the corresponding azide by reaction with sodium azide. The Pd C-catalyzed hydrogenation of the azide functional group in the presence of CHCI3, followed by neutralization of the amine hydrochloride salt with NaOH, furnished the rac-2-amino-5-methoxyindane. Next, rac-2-amino-5-methoxyindane was converted into its diastereomeric amide derivatives by reaction with (R)-mandeloyl chloride. The diastereomeric amide mixture was separated by recrystallization to give the (R,S)- and (R,R)-diastereomers. The absolute configuration of the (R,S)-isomer was determined by X-ray crystallography. The hydrolysis of these diastereomers gave (R)- and (S)-2-amino-5-methoxyindane with high enantiopurity. (C) 2016 Elsevier Ltd.
