Reaction Steps

6-[N-(5-Bromo-2-(2-methylprop-2-en-1-yloxy)benzyl)-N-ethylamino]-3-cyanopyridazine (reference example 13) (0.52 g, 1.34 mmol) in N-methylpyrrolidone (13 ml) was treated with sodium azide (403 mg, 6.1 mmol) followed by triethylammonium chloride (537 mg, 3.9 mmol) and the mixture stirred under argon for 7 hours at 120° C. The mixture was then poured into water and acidified to around pH2. It was then extracted twice with ethyl acetate and the combined organic extracts washed twice with water, dried and evaporated to give a solid. The solid was purified by MPLC, and triturated with a 1:1 mixture of diethyl ether/ethyl acetate to give the title compound as an off-white solid (275 mg, 48%).
