Procedure

114 g of 2-amino-5,2'-dichlorobenzophenone and 100 g of 3,4-dimethoxyphenylsulfonyl chloride are mixed in 300 ml of pyridine. After 4 days at RT, the excess pyridine is evaporated off, the residue is taken up with hydrochloric water and extracted with DCM and the extract is dried and concentrated. The expected product then crystallizes from a DCM/isopropyl ether mixture.
