-78 °C

Distilled (6-bromo-indan-2-yl)-dipropyl-amine (Example 11, 270 mg, 0.91 mmol) was dissolved in dry diethyl ether (20 mL). The solution was kept under argon and cooled to -78° C. A solution of t-BuLi in pentane 1.7M (0.7 mL, 1.20 mmol) was added and the mixture was stired at -78° C. for 1 h. Freshly distilled DMF (0.12 mL, 1.55 mmol) was added at -78° C. and the mixture was stirred at this temperature for 30 min. The reaction mixture was allowed to reach room temperature and stirred for additional 1 h. The organic layer was washed with aq. Na2CO3 (5%), the layers separated, dried (Na2CO3) and evaporated to dryness. MS m/e 245 (11, M+), 216 (100), 145 (17), 117 (22), 72 (21).
