A mixture of 33.2 mg (0.07 mmol) N-(6-Amino-benzothiazol-2-yl)-2,4-dichloro-N-(3,4-dimethoxy-phenyl)-benzamide in 0.7 ml DCM, 18.2 mg (0.18 mmol) NEt3 and 10.3 mg (0.091 mmol) methanesulfonyl chloride in 0.2 ml DCM was reacted for 16 h at room temperature. After evaporation of all volatiles the residue was taken up in DMF/acetonitrile and subjected to preparative HPLC separation on reversed phase eluting with an acetonitrile/water gradient to yield 9.6 mg (25%) of the title compound. MS (m/e): 552.1 (MH+, 100%).
