Reaction Steps

To a stirring mixture of tert-butyl 2-(quinoxalin-5-yl)acetate (200 mg) in HOAc (5 mL) was added 6N HCl (5 mL). The reaction mixture was warmed to 80° C. for 2 h. The crude product mixture was concentrated under reduced pressure to give 2-(quinoxalin-5-yl)acetic acid, which was used in the next reaction without further purification. Method[1], MS (ESI) 189.0 [M+H], Retention time=0.722 min.
