Versuchsvorschrift

To a suspension of (1-(4-fluorobutyl)-1H-imidazo[4,5-b]pyridin-2-yl)methanol 42-5 (958 mg, 4.3 mmol), 1-cyclopropyl-1H-imidazo[4,5-c]pyridin-2(3H)-one 10-d (950 mg, 5.15 mmol) and triphenylphosphine (1350 mg, 5.15 mmol) in 30 ml dry THF was added (E)-diïsopropyl diazene-1,2-dicarboxylate (1.26 ml, 6.43 mmol) at room temperature. The reaction mixture was stirred at room temperature for 16 hours. The precipitate was filtered off and washed with some diethyl ether to obtain the title product as a white powder (1036 mg, 63%).
