Participants

Reaction Steps

To a solution of cyclopropanecarboxylic acid {3-methoxy-4-[5-(5-methyl-3-phenyl-isoxazol-4-yl)-[1,3,4]oxadiazol-2-yl]-phenyl}-amide (138 mg, 0.33 mmol) in DMF (2 mL) was added at ambient temperature potassium bis(trimethylsilyl)amide (0.91 M in THF, 0.44 mL, 0.40 mmol). After the dark brown solution was stirred for 15 min iodomethane (25 μL, 0.40 mmol) was added and the reaction mixture was stirred for 18 h in a closed flask. It was then extracted with water (20 mL) and ethyl acetate (20 mL). The combined organic layers were then washed with aqueous sodium carbonate (saturated, 20 mL), concentrated, dissolved in ethyl acetate (3 mL) and treated with heptane (3 mL). The resulting suspension was filtered off and washed with ethyl acetate:heptane 1:1 (3 mL) affording the title compound (83 mg, 58%) as a white solid. MS: m/e=431.3 [M+H]+.
