Vorschrift

[2-(6-Chloro-3,3-dimethoxy-hexahydrofuro[3,2-b]pyrrole-4-carbonyl)-3-methylbutyl]-carbamic acid tertbutyl ester (78 mg, 0.185 mmol) was deprotected under acidic conditions (acetyl chloride in methanol) as described in Example 4, and the crude pyrrole hydrochloride intermediate was then coupled with the HCl salt of 4-[5-fluoro-2-(4-methyl-piperazin-1-yl)-thiazol-4-yl]-benzoic acid using the HATU conditions as described in Example 2, which gave the title compound (98 mg, 85%). MS m/z 624.2 (M+H)+.
