Reaktionsschritte

Chloroacetyl chloride (4.0 cm3, 50.18 mmol) was added dropwise to a vigorously stirred mixture of 4-amino-1-(2-[indol-3-yl]ethyl)piperidine (12.10 g, 49.8 mmol), potassium carbonate (7.0 g 50.72 mmol) water (100 cm3) and dichloromethane (300 cm3). After 3/4 hour more chloroacetyl chloride (0.5 cm3, 6.27 mmol) and potassium carbonate (0.5 g, 3.62 mmol) were added and stirring continued for a further 3/4 hour. The organic phase was separated, washed with water, dried over magnesium sulphate and evaporated to give 2-chloro-N-[1-[2-(1H-indol-3-yl)ethyl]-4-piperidinyl]acetamide (19.29 g crude)
