Versuchsvorschrift

To a solution of tert-butyl {1-[4-(8-chloro-3-phenyl-1,7-naphthyridin-2-yl)phenyl]cyclobutyl}carbamate (7-4) (288 mg, 0.593 mmol) in 1,4-dioxane (4 mL) was added hydrazine monohydrate (286 mL, 5.93 mmol). The mixture was stirred at 100° C. for 1 h. The mixture was cooled to room temperature, suspended in ethyl acetate, washed with water, dried over sodium sulfate, filtered, and concentrated in vacuo to give tert-butyl{1-[4-(8-hydrazino-3-phenyl-1,7-naphthyridin-2-yl)phenyl]cyclobutyl}carbamate (7-5) as an orange solid.
