Reaction Steps

Potassium cyanide (0.32 g) was added to a cooled (5° C.) solution of 6-[4-(3-dimethylamino-2-methylpropionyl)phenyl]pyridazin-3(2H)-one hydrochloride (1.28 g) and acetic acid (0.25 ml) in water (30 ml). The solution was stirred for 2 hours at less than 23° C., then cooled and a further amount of potassium cyanide (0.32 g) was added. After stirring for one hour the temperature was raised to 50° C. and the reaction mixture was stirred for 2 hours to afford 6-[4-(3-cyano-2-methylpropionyl)phenyl]pyridazin-3(2H)-one (0.61 g), m.p. 196°-201° C.
