To a solution of 100 mg (0.35 mmol) of thioacetic acid S-[1-(5-tert-butyl-isoxazol-3-ylcarbamoyl)-1-methyl-ethyl]ester in ethanol (2 mL) were added 70 mg (0.42 mmol) of 2-(bromomethyl)tetrahydrofuran and 340 μL (1.05 mmol) of sodium ethoxide solution (21% in ethanol) at room temperature. The reaction was heated to 50° C. for 18 h. The reaction mixture was concentrated under reduced pressure and the crude purified by column chromatography (silica, eluent: heptanes, 0-20% ethyl acetate) to afford 82 mg of N-(5-tert-butyl-isoxazol-3-yl)-2-methyl-2-(tetrahydro-furan-2-ylmethylsulfanyl)-propionamide.
