Versuchsvorschrift

To a solution of 4-((3,5-dichloro-N-(4-fluorobenzyl)-2-hydroxyphenylsulfonamido)methyl)-N-methoxy-N-methylbenzamide (0.105 g, 0.20 mmol) in THF (2 mL) was added phenylmagnesium bromide (3M in ether, 0.267 mL, 0.800 mmol). The resulting mixture was stirred at rt overnight. The mixture was quenched by adding cold saturated aq. NH4Ac solution and extracted with DCM. The combined organic extracts were dried and concentrated. The residue was purified by preparative HPLC. The desired fractions were combined, concentrated and lyophilized to dryness to give the title compound (46 mg, 42%) as a tan solid. MS (ESI): 544.1 (M+H)+.
