Reaction Steps

4-Bromo-5-[(1R,2R,3R,5S)-2,6,6-trimethylbicyclo[3.1.1]hept-3-ylamino]pyridazin-3(2H)-one (208 mg, 0.637 mmol) in N,N-dimethylformamide (2 mL) was mixed with ethyl 2-bromopropionate (124 μL, 0.955 mmol) and potassium carbonate (132 mg, 0.955 mmol) at room temperature and stirred at 80° C. for 2 hours. After cooling, the reaction solution was mixed with saturated aqueous ammonium chloride and extracted with ethyl acetate. The resulting organic layer was washed with saturated aqueous ammonium chloride and saturated aqueous sodium chloride, dried over anhydrous magnesium sulfate and evaporated under reduced pressure to give the desired product (149 mg, 55% yield).
