Versuchsvorschrift

(S)-Dimethyl 2-((7-chloro-4-(chloromethyl)-1H-indazol-5-yl)methyl)succinate (250 mg, 0.63 mmol) and (1H-imidazol-2-yl)methanamine dihydrochloride (170 mg, 1.0 mmol) were combined and suspended in acetonitrile (10 mL). Triethylamine (800 μL, 5.7 mmol) was added to the mixture. Reaction was warmed to reflux for 3 hours. Acetic acid (1.5 mL) was added to the mixture. Reaction was heated at reflux for 20 hours. Mixture was cooled to room temperature then diluted with dichloromethane. Mixture was extracted twice with water. Aqueous layer was concentrated in vacuo. Residue was purified by preparatory HPLC. Water was lyophilized off. Remaining residue was passed through a column of Dowex 1×4-200 ion exchange resin eluting methanol. Title compound was recovered as amber residue in 24% yield. MS m/e (M+H)+=388.1.
