Versuchsvorschrift

1.50 g (8.48 mmol) 6-chloropyrimidine-4-carboxylic acid chloride in 50 mL dichloromethane were cooled with a bath of ice/ethanol and combined with 1.20 g (7.81 mmol) 5-chloro-2,3-dihydro-1H-indole. 7.90 mL (7.90 mmol) of a 1M sodium hydroxide solution were added dropwise. The reaction mixture was stirred for 2 h while being cooled and for 1 h at RT. Then 50 mL of an aqueous saturated sodium hydrogen carbonate solution were added. After 10 min stirring the organic phase was separated off and extracted with water (1×30 mL) and with 1 M hydrochloric acid (1×50 mL). The organic phase was dried on magnesium sulphate, filtered and evaporated down i. vac.
