Reaction Steps

A mixture of 3-(4-chloro-phenyl)-5-(3-chloro-1H-pyrrol-2-yl)-[1,2,4]-oxadiazole (30.0 mg, 0.11 mmol), iodomethane (0.08 ml, 0.17 mmol) and potassium carbonate (23 mg, 0.17 mmol) in dimethylformamide (2 ml) was heated at 85° C. for 4 h. It was diluted by water (20 ml) and the mixture was extracted by EtOAc. The extracts were evaporated, and the residue was purified by column chromatography (EtOAc: Hexane=1:1) to give 12.0 mg (37%) of the title compound. 1H NMR (CDCl3): 8.11–8.07 (m, 2H), 7.50–7.45 (m, 2H), 6.84 (d, J=3.0 Hz, 1H), 6.28 (d, J=3.3 Hz, 1H), 4.08 (s, 3H).
