Versuchsvorschrift

Under an argon atmosphere 0.473 g (2.67 mmol) 6-chloropyrimidine-4-carboxylic acid chloride and 0.427 g (3.20 mmol) aluminium trichloride were stirred in 20 mL DCM for 30 min. Then 0.520 g (2.67 mmol) 1,3,3,7-tetramethyl-2,3-dihydro-1H-indole in DCM were added dropwise to the reaction mixture and it was stirred for 45 min at RT, then for 45 min at 40° C. Next, the reaction mixture was decomposed with ice water/sodium hydroxide solution, extracted with DCM and the organic phase was evaporated down i. vac. The residue was taken up in MeOH and purified by preparative HPLC-MS. The fractions containing the product were combined and freeze-dried.
