실험 절차

2-Mercapto benzoxazole (604 mg; 4 mmole) was reacted with 2-(2-bromophenyl)pyridine (936 mg; 4 mmole) in the presence of KOH (224 mg; 4 mmole) in N-methyl pyrrolidine (16 ml). The mixture was heated under reflux for 6 hours, worked up and flash chromatographed (silica), using ethyl acetate/petroleum ether (2/3) eluant to give the sub-title compound as a pale brown oil (52 mg; 4.3%).
