実験手順

Into a 10-mL pressure tank reactor, was placed (S)-2-(methoxymethyl)pyrrolidine (96.45 mg, 0.85 mmol, 5.00 equiv), methyl 3-chloro-2-phenylquinoxaline-6-carboxylate (50 mg, 0.17 mmol, 1.00 equiv), potassium carbonate (46.7 mg, 0.34 mmol, 2.00 equiv), toluene/DMSO (2/0.4 mL). The resulting solution was stirred overnight at 100° C. in an oil bath. The resulting mixture was concentrated under vacuum. The reaction was then quenched by the addition of 10 mL of water. The resulting solution was extracted with 3×30 mL of ethyl acetate and the organic layers combined. The residue was applied onto a silica gel column with ethyl acetate/petroleum ether (1:50). This resulted in 17 mg (27%) of (S)-methyl 3-(2-(methoxymethyl)pyrrolidin-1-yl)-2-phenylquinoxaline-6-carboxylate as a yellow solid.
