Procedure

In hot ethanol (180 ml) was dissolved 8.9 g of 6-[4-(4-(pyridin-3-ylcarbonylamino)butyl)phenyl]pyridazin-3(2H)-one. A 18 % hydrochloric acid-ethanol solution (10 ml) was added to the solution, and the mixture was left to stand at room temperature. Precipitated crystal was collected by filtration and washed with cold ethanol to obtain 9.3 g of 6-[4-(4-(pyridin-3-ylcarbonylamino)butyl)phenyl]pyridazin-3(2H)-one hydrochloride.
