실험 절차

This compound (1.07 g, 85% yield) as a yellow amorphous solid was prepared according to the procedures described for Intermediate 324b, using 2-bromo-1-(6-fluoro-3-(isopropylamino)-2-methylquinoxalin-5-yl)ethanone (619) (840 mg, 2.47 mmol), ethyl 3-(1-((tert-butoxycarbonyl)amino)cyclopropyl)-3-oxopropanoate (604) (804 mg, 2.96 mmol) as the starting materials, followed by the subsequent treatment of the resulting 330a (m/z (ESI, +ve) 531.2 (M+H)+) with NH4OAc (952 mg, 12.35 mmol) in 3 mL of EtOH and 1.5 mL of HOAc at 50° C. for 4 h. m/z (ESI, +ve) 512.2 (M+H)+.
