Reaction Steps

A mixture of 2-[6-bromo-3-pyridazinyl]-(1S,4S)-5-tert-butoxycarbonyl-2,5-diazabicyclo-[2.2.1]-heptane (2.0 g; 5.6 mmol), phenylacetylene (2.4 ml; 22.6 mmol), palladacycle (105 mg; 0.11 mmol), CuI (106 mg; 0.56 mmol), diisopropylethylamine (0.97 ml; 5.6 mmol) and dioxane (20 ml) was stirred at 100° C. for 40 hours. Aqueous sodium hydroxide (50 ml; 1 M) was added. The mixture was extracted with dichloromethane (3×50 ml). Chromatography on silica gel with dichloromethane, methanol and conc. ammonia (89:10:1) gave the title compound as free base. Yield 1.0 g (48%).
