Versuchsvorschrift
30 mg of 4-(1H-Indol-2-yl)-6-(1-methyl-1H-pyrazol-4-yl)-2H-pyridazin-3-one is dissolved in 4 ml of acetone and 22 mg of N-bromosuccinimide is added. The solution is stirred at RT for 20 min and the product is purified by preparative RP-HPLC eluting with a gradient of 0-100% acetonitrile in water (+0.01% trifluoroacetic acid). Yield 14 mg. LC-MS (ES+) 370/372 (M+H)+.
