Procedure

2.0 g (9.5 mmol) 2,6-dichloro-pyridine-4-carboxylic acid chloride in 50 mL DCM were cooled in the ice/EtOH bath and combined with 1.3 g (9.6 mmol) 5-fluoro-2,3-dihydro-1H-indole. In addition 9.6 mL (9.6 mmol) of a 1N aqueous sodium hydroxide solution were added dropwise and the mixture was stirred for 2 h while being cooled and for 1 h at RT. Then 50 mL of a saturated sodium hydrogen carbonate solution were added and the mixture was stirred for a further 10 min. The organic phase was separated off, extracted with 1N aqueous hydrochloric acid solution and with water, dried on sodium sulphate and evaporated down.
