Reaction Steps

A mixture of 3-(quinoxalin-2-yl)propanoic acid (530 mg, 2.6 mmol) and 2-aminobenzenethiol (390 mg, 3.12 mmol) in PPA (7 g) was heated to 120° C. and stirred for 10 minutes. The reaction mixture was cooled and aqueous NaOH (20 mL) was added. The mixture was extracted with DCM (2×20 mL). The combined organic layers were dried over sodium sulfate, filtered, concentrated and then purified by prep-TLC to give 2-(2-(quinoxalin-2-yl)ethyl)benzo[d]thiazole as a yellow solid. (38 mg). MS (ESI) m/z 318 (M+H+).
