Prepared as for Example 101b using N-(5-bromo-3-methoxy-2-pyrazinyl)-2,3-dichloro-N-[{2-(trimethylsilanyl)ethoxy}methyl]benzenesulphonamide (Example 55a) (0.4 g) and 2-mercapto-N-methylacetamide (0.1 g). The intermediate product containing the SEM (2-[trimethylsilyl]ethoxymethyl) group was purified by silica gel chromatography eluting with ethyl acetate/iso-hexane mixtures. Deprotection as for Example 101b gave the title compound. Yield 0.05 g.
