反応手順

1.5 g (8.48 mmol) 6-chloropyrimidine-4-carboxylic acid chloride in 50 mL dichloromethane were cooled with an ice/ethanol bath and combined with 1.2 g (7.81 mmol) 5-chloro-2,3-dihydro-1H-indole. 7.9 mL (7.9 mmol) of a 1M sodium hydroxide solution were added dropwise. The reaction mixture was stirred for 2 h with cooling and for 1 h at RT. The man 50 mL of an aqueous saturated sodium hydrogen carbonate solution were added. After 10 min stirring the organic phase was separated off and washed with water and 1 M hydrochloric acid. The organic phases was dried on magnesium sulphate, filtered and evaporated down i.vac.
