Reaction Steps

100 mg of 3-(1-methyl-1H-pyrazol-4-yl)-2-(3-oxo-6-pyridin-4-yl-2,3-dihydro-pyridazin-4-yl)-1H-indole-5-carboxylic acid is dissolved in 3 ml of dichloromethane and 139 mg of N-ethylmorpholine and 43.6 mg of TOTU (O-((ethoxycarbonyl)-cyanomehyleneamino)-N,N, N′,N′-tetramethyluroniumtetrafluoro) is added. After 5 minutes 34 mg of 1-cyclopropyl-piperidin-4-ylamine is added. The reaction is stirred for 48 h at RT. The product is purified by preparative RP-HPLC eluting with a gradient of 0-100% acetonitrile in water (+0.01% trifluoroacetic acid). Yield 47 mg. LC-MS (ES+) 535 (M+H)+.
