Komponenten

Versuchsvorschrift

To a mixture of compound from step B (68 mg, 0.189 mmol) and NMM (38 mg, 0.37 mmol) in DCM (7 mL) was added methylsulfonyl chloride (32 mg, 0.283 mmol) dropwise. Then the mixture was stirred at room temperature for 4 h. The reaction was quenched with saturated ammonium chloride solution, extracted with ethyl acetate (50 mL). The organic layer was washed with brine, dried over sodium sulfate, filtered and evaporated. The residue was purified by silica gel chromatography eluting with PE/EA (10/1 to 3/1, v/v) to afford the title compound as a white solid. LC/MS m/z=439.0[M+H]+.
