The present invention provides a process for the manufacture of an arylmethyl-sulfonylarene, R
1
CH
2
SO
2
R
2
, wherein R
1
and R
2
are each independently an optionally substituted phenyl or naphthyl group which process comprises reacting an arylmethylhalide, R
1
CH
2
-Hal wherein R
1
is as defined hereinabove and Hal is Cl, Br or I with a sodium arylsulfinate R
2
SO
2
Na wherein R
2
is as defined hereinabove in the presence of a base optionally in the presence of a solvent.
Also provided is the use of the inventive process in the manufacture of a 3-arylsulfonylindazole 5-HT6 ligand.
                            本发明提供了一种制备芳基甲基磺酰基
芳烃R1CH2SO2R2的方法,其中R1和R2各自独立地为可选择取代的苯基或
萘基。该方法包括将芳基甲基卤化物R1CH2-Hal(其中R1如上所定义,Hal为Cl、Br或I)与
钠芳基
磺酸盐R2SO2Na(其中R2如上所定义)在碱的存在下反应,可选择在溶剂的存在下进行。本发明还提供了将该创新过程用于制备3-芳基磺酰基
吲哚5-HT6
配体的用途。
