Reaction Steps

A solution of the 6-chloro-4-(1,4-dioxaspiro[4.5]dec-6-en-6-yl)pyridazin-3-amine (0.10 g, 0.37 mmol) prepared in Example 82b, ammonium formate (0.14 g, 2.24 mmol) and palladium carbon (10%; 0.10 g) in ethanol (3.7 mL) was stirred at 80° C. for 4 hours. After allowing to cool, the reaction solution was filtered through celite and concentrated to yield the title compound in a crude form.
