Chloroacetonitrile → {5-Chloro-2-[4-(2,6-dimethoxy-phenyl)-piperidine-1-carbonyl]-indol-1-yl}-acetonitrile

Participants

Reaction Steps

To a stirred solution of 40 mg (0.10 mmol) of (5-chloro-1H-indol-2-yl)-[4-(2,6-dimethoxy-phenyl)-piperidin-1-yl]-methanone in DMF (3 ml) at RT was added 5 mg (0.11 mmol) of NaH (in oil, 55%). After 20 minutes, 8 mg (0.10 mmol) of chloro-acetonitrile was added and stirring was continued over night. The reaction mixture was concentrated in vacuo and purification by preparative HPLC (30% CH3CN/H2O) afforded 9 mg (18%) of {5-chloro-2-[4-(2,6-dimethoxy-phenyl)-piperidine-1-carbonyl]-indol-1-yl}-acetonitrile as a white solid.
