Vorschrift

177 mg N-(2,6-dimethoxybenzyl)-N′-(4-pyrrolidine-2-yl-1,3-thiazole-2-yl)guanidine, Example 147 free base, 100 mg of benzyl bromide and 870 mg polymer-bound triazabicyclodecene (1.3 mmol/g, Argonaut) were shaken in 20 ml acetonitrile overnight at room temperature. Chromatography on silica gel (dichloromethane/methanol 0-5%) of the residue obtained following evaporation concentration yielded 112 mg of a white solid; ESI-MS [M+H+]=452.15.
