Reaction Steps

A solution of methyl 3-(4-(3-chlorophenyl)piperazin-1-yl)-2-phenylquinoxaline-6-carboxylate (186.7 mg, 0.41 mmol, 1.00 equiv) and sodium hydroxide (82 mg, 2.05 mmol, 5.00 equiv) in tetrahydrofuran/MeOH (1:1) (25 mL) was placed in a 50-mL round bottom flask, stirred for 8 h at 50° C. in an oil bath, and then concentrated under vacuum. This resulted in 177.7 mg (95%) of 3-(4-(3-chlorophenyl)piperazin-1-yl)-2-phenylquinoxaline-6-carboxylic acid as a yellow solid.
