To a solution of 100 mg (0.352 mmol) of thioacetic acid S-[1-(5-tert-butyl-isoxazol-3-ylcarbamoyl)-1-methyl-ethyl]ester (synthesized according to Method F, step 1) in ethanol (2 mL) were added 126 mg (0.704 mmol) of 2-(bromomethyl)tetrahydropyran and 76 mg (1.41 mmol) of sodium methoxide at room temperature. The reaction was heated to 130° C. for 0.5 h within a microwave (CEM Discover). The reaction mixture was concentrated under reduced pressure. The residue was dissolved in DCM (5 ml) and washed with saturated aqueous NaHCO3 solution (5 ml). The organic phase was dried (Na2SO4), filtered and concentrated under reduced pressure to yield 119 mg of N-(5-tert-butyl-isoxazol-3-yl)-2-methyl-2-(tetrahydro-pyran-2-ylmethylsulfanyl)-propionamide.
