Participants

Procedure

To a solution of 6-Bromo-2-chloro-quinoxaline (0.45 g, 1 eq, 1.85 mmol) in DMSO (6 mL), was added (R)-1-phenylethanamine (0.67 g, 3 eq, 5.55 mmol) at room temperature. The mixture was stirred overnight. After completion of the reaction (confirmed by TLC), cold water (40 mL) was added to the reaction mixture and this was stirred for 1 hour at room temperature. The precipitate was filtered off, washed with water (10 mL) and then dried under vacuum to afford the title compound (0.48 g, 79%).
