Versuchsvorschrift
1-(3,4-dichlorobenzyl)-3-(4-(iodomethyl)thiazol-2-yl)urea (Intermediate 6) was taken up in tetrahydrofuran and an excess of the 2,4-dimethoxy-benzylamine (20 eq.) was added. The reaction was allowed to stir overnight at room temperature. The volatiles were removed in vacuo. Resulting oil triturated with water to give a gooey solid. Water was decanted off and resulting residue was purified by column chromatography using 0-8% gradient of 7 N ammonia/MeOH and DCM to give 1-(3,4-Dichloro-benzyl)-3-{4-[(2,4-dimethoxy-benzylamino)-methyl]-thiazol-2-yl}-urea.
