実験手順

Under an inert atmosphere a flask is charged with [2-(5-bromo-1H-indol-3-yl)-ethyl]-dimethyl-amine (Example 3) (1.0 g, 3.74 mmol), zink cyanide (0.235 g, 2 mmol), Pd2(dba)3xCHCl3 (0.194 mg, 5 mol %), dppf (bis-diphenylphosphino ferrrocene) (0.207 g, 0.374 mmol, 10 mol %), and DMF (12 mL). The orange slurry is heated to 110° C. and stirred for 21 hours. To the black suspension which has formed, THF (100 mL) is added, and this is extracted with 1 N NaOH (100 mL). The organic layer is washed with water twice (50 mL each), dried and removal of the solvent gives the title product (0.67 g, 84%) as brown solid.
