80 °C

At RT, 8.8 ml (9.0 g, 180.2 mmol) of hydrazine hydrate are added dropwise with stirring to a solution of 3.9 g (18.0 mmol) of 4-(6-chloropyrimidin-4-yl)-1,4-oxazepane in 25 ml of ethanol. After 16 h of stirring at 80° C., the reaction solution is concentrated under reduced pressure. The residue is triturated with cold ethanol, the precipitated solid is filtered off and the filter residue is washed with 25 ml of diethyl ether. The product is dried under reduced pressure. Yield: 1.4 g (36% of theory)
