Under a nitrogen atmosphere 120 mg (3.00 mmol) sodium hydride (60% in mineral oil) were added batchwise to 380 mg (2.90 mmol) 3-methylindole in 15 mL THF and the mixture was stirred for 30 min at RT. 500 mg (2.83 mmol) 6-chloropyrimidine-4-carboxylic acid chloride were added batchwise and then the reaction mixture was stirred for 2 h at RT. Then 50 mL EtOAc were added and the mixture was washed with 50 mL saturated sodium hydrogen carbonate solution (1×), 30 mL water and with 50 mL 1 M hydrochloric acid. The organic phase was dried on sodium sulphate, filtered and then evaporated down i. vac. The product was used in the next step without further purification.
