Reaction Conditions

Reaction Steps

60 mg of the amine prepared in Example 1a were first dissolved in 2 ml DCM at 0° C. 0.034 ml of triethylamine and 43.2 mg of 4-[(trifluoromethyl)sulphanyl]benzoyl chloride were then added and the mixture stirred for 2 hrs at 0° C. The reaction mixture was then diluted with DCM and washed with 1-molar hydrochloric acid, saturated sodium hydrogen carbonate solution (pH 9) and saturated sodium chloride solution. The organic phase was dried over sodium sulphate, filtered and concentrated. The residue was purified chromatographically on the Biotage SP4. Gradient: DCM/Methanol 0-10%. The product fraction was taken up in ethyl acetate and extracted twice with saturated sodium hydrogen carbonate solution. The organic phase was concentrated and the residue again purified by HPLC. Yield: 26.5 mg of the title compound.
