実験手順

A solution of 200 mg (1.12 mmol) of 5-amino-6-nitroindan and 1.14 g (6.01 mmol) of SnCl2 in 8 mL of ethanol was heated at 70° C. for 2 h. It was evaporated to remove the ethanol. The residue was treated with 40% aqueous NaOH to pH=12. The mixture was diluted with 4 mL of water and extracted with CHCl3 (3×10 mL). The extract was dried (MgSO4) and evaporated to leave a yellow crystalline solid (162 mg, 97%). 1H NMR (CDCl3), 2.012 (m, 2), 2.773 (t, 4, J=7.25), 3.301 (sb, 4), 6.614 (s, 2).
