Reaction Steps
A solution of methyl 5-chloro-3-methylpyrazine-2-carboxylate (0.117 g, 0.627 mmol) (Step 3 of Intermediate 24) and sodium hydroxide 5N (0.150 ml, 0.752 mmol) in dioxane (5 mL) was stirred at room temperature for 30 minutes. The reaction mixture was acidified with 2N HCl to pH 4 and extracted with EtOAc (2×). The combined organic extracts were dried over Na2SO4 and the filtrate was concentrated to afford the title compound (91.0 mg, 84%). MS m/z=172.9 (M+H)+.
