Procedure

Under an N2 atmosphere 39 μL (0.5 mmol) methanesulphonic acid chloride are added to a solution of 100 mg (0.24 mmol) 5-[5-(4-chloro-phenyl)-pyridin-2-ylethynyl]-2-(2-pyrrolidin-1-yl-ethoxy)-phenylamine and 161 μL (2 mmol) pyridine in 10 mL DCM and the reaction mixture is stirred for 2 h at RT. To complete the reaction a further 160 μL pyridine and 39 μL methanesulphonic acid chloride are added and the mixture is stirred overnight. It is combined with 10% Na2CO3 solution, the organic phase is separated off and the solvent is eliminated i.vac. The residue is purified by HPLC.
