実験手順

To a solution of 200 mg (0.654 mmol) of thioacetic acid S-[1-methyl-1-(5-trifluoromethyl-pyridin-2-ylcarbamoyl)-ethyl]ester (synthesized according to Method F, step 1) in ethanol (2 mL) were added 363 mg (1.31 mmol) of 4-bromomethyl-piperidine-1-carboxylic acid tert-butyl ester and 141 mg (2.61 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 (4 mL) and washed with saturated aqueous NaHCO3 solution (5 mL). The organic phase was dried over Na2SO4, filtered and the filtrate was concentrated under reduced pressure to yield 375 mg of 4-[1-methyl-1-(5-trifluoromethyl-pyridin-2-ylcarbamoyl)-ethylsulfanylmethyl]-piperidine-1-carboxylic acid tert-butyl ester.
