Reaction Steps

Methyl 4-(3-amino-6-(1,4-dioxaspiro[4.5]dec-7-en-8-yl)pyrazin-2-yl)-2-fluorobenzoate (6.1 g, 15.83 mmol) was dissolved in MeOH (150 mL) and EtOAc (80 mL) the reaction mixture was flushed with N2 for 15 min, Then Pd—C (DEGASSA) (6 g, 5.64 mmol) was added, the reaction mixture was then charged with hydrogen balloon and stirred at room temperature overnight. The reaction mixture was filtered through Celite, which was washed with EtOAc and methanol. The filtrate was concentrated to yield the crude product, which was used in the next step reaction without purification. LCMS (m/z): 388.0 (MH+), 0.79 min.
