Reaction Steps
To 104 mg (0.25 mmol) of (S)-tert-butyl(1-(4-(imidazo[1,2-b]pyridazin-6-yl)piperazin-1-yl)-4-methyl-1-oxopentan-2-yl)carbamate dissolved in 5 mL of AcOH was added bromine (48 mg, 0.3 mmol) and the resulting mixture was stirred at room temperature. After 0.25 hr, the reaction was done, and concentrated by rotavap and then by high vacuum pump to obtain 139 mg (100% yield) of mono-acetic acid salt of the desired product.
