Procedure
2.93 g of (S)-5-bromo-indan-2-ylamine were prepared as described for the (R)enantiomer starting from 12.5 of racemic 5-bromo-indan-2-ylamine and the corresponding (1R)-(−)-campher-sulfonic acid. The enantiomeric purity was checked via chiral HPLC on a DAICEL Chiralcel OJ column (4.6×250 mm) using n-hexane:isopropanol:triethylamine (90:10:0.1) as eluent: 99% (S)-1% (R).
