Versuchsvorschrift
At RT, 27.2 ml (27.9 g, 279.1 mmol) of hydrazine hydrate are added dropwise with stirring to a solution of 10.4 g (55.8 mmol) of 1-(6-chloropyrimidin-4-yl)azetidin-3-ol in 100 ml of ethanol. The reaction solution is stirred at 80° C. for 16 h. For work-up, the mixture is concentrated under reduced pressure, and the precipitate is filtered off and washed twice with in each case 10 ml of ethanol. Yield: 2.0 g (19% of theory)
