Procedure

To a solution of 172 mg (0.52 mmol) of N-(5-tert-butyl-isoxazol-3-yl)-2-methyl-2-(pyrrolidin-3-ylmethylsulfanyl)-propionamide (prepared according to Method I, step 1) and 0.18 mL (1.04 mmol) of N,N-diisopropylethylamine in THF were added 0.16 mL (2.11 mmol) of methanesulfonyl chloride. The reaction was heated within a microwave to 90° C. for 0.5 h. The 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 layer was dried over Na2SO4, filtered and the filtrate was concentrated under reduced pressure to afford 168 mg of N-(5-tert-butyl-isoxazol-3-yl)-2-(1-methanesulfonyl-pyrrolidin-3-ylmethylsulfanyl)-2-methyl-propionamide, which was used in the next step without further purification.
